二(1,8-萘啶氮氧化物)合硝酸铜(Ⅱ)的晶体结构

CRYSTAL STRCTURE OF BIS(1,8-NAPHTHYRIDINE-N-OXIDE)COPPER(Ⅱ)NITRATE

1,8-萘啶氮氧化物(简写napyo)是一种配位能力较强的中性配体,关于它与金属离子形成的配合物已有报道.但工作主要集中在配合物的合成及性质的研究,它与金属离子形成的配合物的晶体结构至今未见报道.本工作旨在探讨1,8-萘啶氮氧化物与铜(Ⅱ)的配合物中配体与金属离子的配位情况以及铜(Ⅱ)的配位构型.

The crystal and molecular structure of the title compound was determined fromsingle crystal X-ray diffraction. The complex crystallizes in monoclinic space groupP2_(1/n) with Z= 2. Lattice parameters are: a = 7.768(2), b= 13.976(2), c= 9.045(3)A,6 = 113.12(3)°. The structure was solved by the direct method and Fourier techniques andrefined full-matrix least-squares to R = 0.035 for 1579 reflections. The Cu^(2+) ion is 6-ooordin te, being bonded to two oxygen toms from two unidentate nitrate groups andtwo nitrogen atoms and two oxygen atoms from two organic ligands. Each Cu^(2+) ion iscoordinated In a distorted octahedral configuration.
