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).
在标题化合物乙腈溶剂化物[Zn(C₃₄H₄₂N₄O₂)(C₂H₆OS)]·CH₃CN中，锌原子呈畸变的四方锥几何构型，其底面由四齿席夫碱的N₂O₂原子确定，而二甲亚砜的O原子处于顶端位置。席夫碱配体的四齿配位模式形成了一个五元ZnN₂C₂螯合环，该环呈信封式构象，锌原子位于折边上，还有两个六元ZnOC₄N螯合环，其中一个近似平面（均方根偏差 = 0.054 Å），但另一个有明显的褶皱（均方根偏差 = 0.203 Å）。
