2,2′-(Ethylenedioxy)dibenzaldehyde bis(thiosemicarbazone)]nickel(II) diperchlorate methanol disolvate

Abstract

The title compound, [Ni(C18H18N6O2S2)](ClO4)2·2CH4O, (I), has been prepared by the reaction of 2,2′-(ethyl­ene­dioxy)­dibenz­aldehyde bis­(thio­semicarbazone), L, with nickel(II) perchlorate. The chemical structural unit, which is twice the asymmetric unit of (I), consists of one NiII ion, one ligand L, two methanol solvent mol­ecules and two uncoordinated perchlorate anions. The Ni atom lies on a crystallographic twofold axis of rotation. The ligand L coordinates to the central Ni atom through two O atoms, two S atoms and two N atoms, giving a distorted octahedral environment. The S and O atoms occupy equatorial positions, and are nearly coplanar with the nickel, while the two N atoms occupy axial positions, with the N—Ni—N angle being 177.06 (18)°.
