چکیده
The Zn atom in the title acetonitrile solvate, [Zn(C(34)H(42)N(4)O(2))(C(2)H(6)OS)]·CH(3)CN, exists in a distorted square-pyramidal geometry with the basal plane defined by the N(2)O(2) atoms of the tetra-dentate Schiff base and with the dimethyl sulfoxide O atom in the apical position. The tetra-dentate mode of coordination of the Schiff base ligand leads to a five-membered ZnN(2)C(2) chelate ring which adopts an envelope conformation with the Zn atom at the flap, and two six-membered ZnOC(4)N 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).
