(Dimethyl sulfoxide-κO){44′66′-tetra-tert-butyl-22′-12-dicyano­ethene-12-diylbis(nitrilo­methyl­idyne)diphenolato-κ4 ONN′O′}zinc(II) acetonitrile monosolvate

摘要

The Zn atom in the title acetonitrile solvate, [Zn(C34H42N4O2)(C2H6OS)]·CH3CN, exists in a distorted square-pyramidal geometry with the basal plane defined by the N2O2 atoms of the tetra­dentate Schiff base and with the dimethyl sulfoxide O atom in the apical position. The tetra­dentate mode of coordination of the Schiff base ligand leads to a five-membered ZnN2C2 chelate ring which adopts an envelope conformation with the Zn atom at the flap, and two six-membered ZnOC4N chelate rings, one of which is approximately planar (r.m.s. deviation = 0.054 Å) but the other has significant puckering (r.m.s. deviation = 0.203 Å).
