0 0 0 ┃ ↗ ↖ ┃ Mo(V) chelates containing MoO and Mo Mo group with glycoletherdiaminetetraa- ↘ ↙ 0 cetic acid(GEDTA), triethylenetetraminehexaacetic acid(TTHA) and iminodiacetic acid(IDA) have been synthesized and characterized by elemental analysis, absorption spectra and differential thermal analysis. For each of these chelates, the band at 2,900-3,000cm-1 assigned to C-H stretching in the CH2 groups and at 1,570-1,660cm-1 region for the antisymmetrical vibration of the coo- group are observed. In the UV-visiblespectrum, these chelates have two absorption peaks. Dissociation occurs according to [H+] in perchloric acid Solution.

Schiff Base 리간드의 몰리브덴 착물 합성과 그 성질
구본권,김정숙 대구효성가톨릭대학교 1992 연구논문집 Vol.45 No.1
Six-coordinate molybdenum(V) complexes [MoOCI(L)(MeOH)], where L=the tridentate schiff base dianions derived from the condensation reaction between various salicylaldehydes and 2-aminophenol have been synthesized. The structures of the complexes have been determined by elemental analysis, conductivity, U.V.-visible, I.R., and ¹H n.m.r.. The coordination around the molybdenum is distorted octahedral. A tridentate ligand containing the ONO donor atoms occupies meridional positions with the N atom trans to the terminal oxo group. The electrochemical behaviors for the complexes have been also investigated by cyclic voltammetry in dimethylsulfoxide.

Schiff Base 리간드의 몰리브텐(0)- 니트로실 착물 합성과 분광학적 성질
구본권,윤은미 대구효성가톨릭대학교 1997 연구논문집 Vol.55 No.2
Molybdenum(0) - nitrosyl complexes of Schiff bases derived from salicylaldehyde, 3-methoxysalicylaldehyde, 5-nitrosalicylaldehyde, 5-bromosalicylaldehyde, 5,6-benzosalicylaldehyde, and 2-aminobenzenthiol have been prepared in one step by the reaction of [Mo(NO)₂(acac)₂](acac = acetylacetone) and the Schiff bases. The infrared spectral absorptions at ~1760cm-¹ and ~1640cm-¹ indicated that the nitrogene monoxide groups were coordinated as NO+ and were cis to each other. The ¹H-NMR spectral studies were also presented. The analytical and spectral data suggested that the complexes are of the type [Mo(NO)₂(LH)₂](LH=Schiff bases) in which Schiff bases behave as monobasic bidentate ligands and coordinate to molybdenum through the azomethine nitrogen and phenolic oxygen of the saicylaldehyde moiety.

트리- 및 테트라메틸렌디아민테트라아세테이트의 몰리브데늄(Ⅵ) 착물
具本權 대구효성가톨릭대학교 1984 연구논문집 Vol.28 No.2
Synthesis of new complexes of Mo(Ⅳ), Na?[Mo?O? trdta]·8H?O and Na?[Mo?O tdta]·8H?O, has been carried out, where trdta and tdta represent(OOCCH?)? N(CH?)?N(CH?COO)? and (OOCCH?)?N(CH?)?N(CH?COO)?. The elemental anslysis, infrared, nudear magnetic resonance and visible and ultraviolet absorption spectra were measured. The infrared and the NMR spectra of Mo(Ⅳ) chclates with trdta and tdta indicate that coordination occurs at carboxylate group and nitrogen sites in these chclates.

S-Methyl-3-(2-hydroxyphenyl)methylenedithiocarbazate 와 그 유도체 텡스텐(Ⅵ)산소 착물
모성종,구본권 대구효성가톨릭대학교 1998 연구논문집 Vol.57 No.2
A gneral method for the preparation of oxotungsten(Ⅳ) complexes of the type[WOLC1₂](Where LH₂= the Schiff base derived from salicylaldehyde and its derivatives, and S-methyldithiocarbazate) usingWOC1₄as a precursor, is described. The characterizationis performed by means of the usual physicochemical techniquences. In the complex the coordination around tungsten atom is approximately octahedral with two chloride ligands in the trans position, and the remaining two equatorial sites and two axial positions occupied by ONS donor atom set of L and the terminal oxygen. Consequently the imino nitrogen of the L ligand is trans to the terminal oxygen.

박유철,구본권 慶北大學校 産業開發硏究所 1981 硏究報告 Vol.9 No.-
Absorption spectra and kinetics of solvated electrons in solvent mixtures give some information about the properties of solvated electrons. In this paper the reaction between solvated electrons and benzene in several tetrahydrofuran/water mixtures will be investigated in the temperature range 260K<T<325K by Laser-Flash-Spectroscopy. Solvent and temperature dependence of absorption spectra will be discussed. In this study, it is found that the maximum wavelengths of the absorption shectrum were increased with increasing THF content and temperature.

몰리브뎀(Ⅴ)의 아닐린, 톨루이딘 및 트리에틸아민 착물의 합성과 그 성질
오상오,구본권 慶北大學校 1982 論文集 Vol.33 No.-
[MoO(NCS)_5]^2-의 아닐린늄, 톨루이딘늄 및 트리에틸암모늄염을 합성하고 원소분석, 전기전도도, 흡수스펙트라, 자화율 측정으로부터 분자식과 그 성질을 조사하였다. 이들 염에서 아닐린, 톨루이딘 그리고 트리에틸아민은 배위자가 아닌 양이온으로 존재하며 착물의 음이온은 티오시아나토의 질소가 몰리브덴에 결합되어 있음을 알 수 있었다. 이들 착물은 상자성체이며 가시 및 자외선 영역에서 d-d 전이와 전하이동전이에 해당하는 3개의 흡수띠가 관찰되었다. Anilinium, toluidinium and triethylammonium salts containing [MoO(NCS)_5]^2- have been synthesized. The complexes have been characterized by elemental analysis, electrical conductivity, absorption spectra, and magnetic susceptibility measurement. In these salts, aniline, toluidine and triethylamine are not ligand but counter ion for [MoO(NCS)_5]^2-. The complex anions are mononuclear containing N-bonded NCS^- ligand. These salts are paramagnetism and three absorption peaks corresponding to d-d and charge transfer transition in the UV-visible region were observed.

磁性浦捉劑 δ-FeOOH의 製造와 이를 利用한 重金屬이온의 處理
오상오,박유철,구본권 慶北大學校 1980 論文集 Vol.30 No.-
자성포착제 δ-FeOOH는 황산철과 수산화나트륨 수용액을 반응시켜 얻은 수산화철 용액에 오존을 급격히 통하게 하여 합성했다. 실온에서 산화시간을 일정하게 하고 황산철에 대한 수산화나트륨의 농도 변화에 따른 δ-FeOOH의 생성에 대한 최적조건을 조사했다. 이러한 조건하에서 만든 산화철로써 폐수중의 중금속이온 즉 Cd^2+, Cr^6+, As^3+, Pb^2+, Hg^2+를 처리하고 그 결과를 보고한다. Magnetic seeding material, δ-FeOOH was prepared by passing through ozone to Fe(OH)_2, which is made by reaction the aqueous solution of the ferrous sulfate with the sodium hydroxide. In order to find the condition of formation of δ-FeOOH at room temperature, the variation of concentration of sodium hydroxide against ferrous sulfate was considered at constant oxidation time. Under these conditions, the degree of treatment for heavy metal ions, such as Cd^2+, Cr^6+, As^3+, Pb^2+, and Hg^2+ in waste water were discussed.
