다국어 초록 (Multilingual Abstract)

A new copper(II) complex, Cu(dpb)(NO$_3$)$_2$(H$_2$O) (dpb=2,2'-dipyridylbenzylamine) (1) was synthesized from the reaction of Cu(NO$_3$)$_2$·3H$_2$O and dpb in ethanol solution followed by recrystallization in acetonitrile. The structure of 1 was determined by X-ray diffraction methods. The single crystal structure was characterized as follows: space group P2$_1$/c, Z=4, a=12.501(9)$\AA$, b=9.231(10)$\AA$, c=17.119(6)$\AA$, $\alpha$=90$^{\circ}$, $\beta$=107.33(4)$^{\circ}$, $\gamma$=90$^{\circ}$, V=1885.8(2)$\AA^3$, R$_1$=0.0647, $_{w}R$_2$$=0.1866 for 3258 reflections. Compound was a typical paramagnetic copper(II) complex coordinated by 2,2'-dipyridylamine derivative ligand, which was confirmed by EPR, NMR, UV/VIS, and IR spectroscopy.
