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 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).

A mixture of diaminemaleonitrile (0.1 g, 0.93 mmol), 3,5-di-tert-butyl-2-hydroxybenzaldehyde (0.1 g, 1.86 mmol), zinc(II) acetate dihydrate (0.2 g, 0.93 mmol) and ethanol (5 ml) were placed in a glass Petri dish and capped with a glass cover. The dish was placed in a microwave oven (700 W) and irradiated for 1 min. The reaction mixture was cooled and washed with 15 ml of ethanol. The purple solid was filtered off and washed with ethanol. Re-crystallization was by slow evaporation of an acetonitrile/dimethyl sulfoxide (90/10 v/v) solution which yielded purple blocks of (I). Yield: 70%.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Metal complexes with salicylaldiminato ligands are promising materials for optoelectronic applications due to their outstanding photo- and electro-luminescent properties (Liuzzo et al., 2010; Shirai et al., 2000). One of the main appeals of this class of coordination complexes is that molecular engineering permits systematically the optimizing of spectroscopic and chemical properties. This chemical flexibility allows for the design of systems that respond to specific environmental variables. Recently, zinc complexes have been introduced to OLED's (organic light-emitting diodes) and recognized as useful electron transport materials (Chen et al., 2009). The above motivated the synthesis and structural characterization of the title complex, (I).
The Zn atom in (I), Fig. 1, is tetracoordinated by the N2O2 donor atoms of the tetradentate Schiff-base ligand and the O atom derived from the dimethyl sulfoxide ligand, Table 1; the asymmetric unit is completed by a non-coordinating acetonitrile molecule. The resulting N2O3 donor set is based on a square pyramidal arrangement with the dimethyl sulfoxide-O3 atom occupying an axial site. The value of τ = 0.16 compares with τ = 0 and 1.0 for ideal square pyramidal and trigonal bipyramidal geometries, respectively (Addison et al., 1984). The r.m.s. deviation of the O1, O2, N1 and N2 atoms from their least-squares plane is 0.0836 Å and the Zn atom lies 0.3976 (7) Å out of the plane towards the O3 atom. The tetradentate mode of coordination of the Schiff-base leads to the formation of a five- and two six-membered rings. The former has a conformation based on an envelope on Zn (Spek, 2009). While the chelate ring involving the O1 atom is approximately planar (r.m.s. = 0.054 Å), there is significantly more distortion in the O2-containing chelate ring (r.m.s. = 0.203 Å). Schiff-base ligands derived from diaminomaleonitrile have been documented and shown to adopt comparable coordination modes towards transition metals (MacLachlan et al., 1996).
