The complete molecule of the title compound, [Zn(C4H8NS2)2(C10H8N2)], is generated by crystallographic twofold symmetry, with the Zn atom lying on the rotation axis; the axis also bisects the central C—C bond of the 2,2′-bipyridine molecule. The metal atom is chelated by two S,S′-bidentate dithiocarbamate anions and the N,N′-bidentate heterocycle, resulting in a distorted cis-ZnN2S4 octahedral geometry. The methyl and ethyl groups of the anion are statistically disordered.

Zinc chloride (10 mmol), ethylmethylamine (20 mmol), carbon disulfide (20 mmol), 2,2'-bipyridine and ammonia (10 ml) were reacted in ethanol (30 ml) at 277 K to produce a white solid. This was collected and recrystallized from ethanol to yield colourless blocks of (I).
Carbon-bound H-atoms were placed in calculated positions (C—H 0.93 to 0.97 Å) and were included in the
in the riding model approximation, with U(H) set to 1.2 to 1.5U(C). The methyl group is disordered with respect to the ethyl group. Both were refined as ethyl groups, but the methyl carbon atoms were refined with 0.5 occupancy each. The carbon-carbon distance was restrained to 1.50±0.01 Å; the anisotorpic temperature factors of the half-occupancy atoms were restrained to be nearly isotropic.For other 2,2'-bipyridine adducts of zinc dithioarbamates, see: Ali et al.
