Abstract

[Zn(mipit)

4][BF4]2 (1) and [Zn(mnbit)4][BF4]2 (2) were synthesized and characterized via std. solid and soln. state methods including single crystal x-ray crystallog. (mipit = 1-methyl-3-(2-propyl)-2(3H)-imidazolethione and mnbit = 1-methyl-3-(1-butyl)-2(3H)-imidazolethione). Compd. 1 crystallizes in monoclinic space group P21/n with a 11.804(2), b 16.710(3), c 25.763(5) Å, γ 90.14(3)° and Z = 4, whereas compd. 2 crystallizes in tetragonal space group I.hivin.4 with a = b 11.6517(16), c 16.820(3) Å, and Z = 2. Both complexes are high melting, colorless water sol. 2:1 electrolyte solids that state have flattened tetrahedral ZnS4 coordination geometry. The iso-Pr analog is slightly more distorted than the Bu analog, and the degree of distortion is not directly related to the steric bulk of the ligand.
