The Crystal Structure of Chloro(1,10-phenanthroline-2-carboxamide Oxime)copper(II) Nitrate

Abstract

In chloro(1,10-phenanthroline-2-carboxamide oxime)copper(II) nitrate thecopper atom adopts a distorted square pyramidal structure with bridging chlorogroups producing a zigzag chain in which each tridentate phenanthroline amideoxime group coordinates through the oxime nitrogen atom and is essentiallyplanar. The planes of the tridentates are almost parallel, giving a stackedarray of the ligands within the chain. The nitrate ions link chains throughhydrogen bonding with the amino and oxime hydrogen atoms of the carboxamideoxime group. The crystals are monoclinic, space group P2₁/c,a9·2199(6), b21·794(1), c 7·2889(4) Å, β99· 900(3)˚, Z 4.
