Metal Substitution and Solvomorphism in Alkylthiolate-Bridged Zn and HgZn Metal Clusters.

The impact of substituting Hg(II) for Zn(II) in a thiolate-bridged trinuclear cluster with parallels to a metallothionein metal cluster was investigated. A new solvomorph of [Zn(Zn)](ClO) () ( = -(2-pyridylmethyl)--(2-(ethylthiolato)-amine) and five solvomorphs of a new compound [Hg(Zn)](ClO) () were characterized by single-crystal X-ray crystallography. The interplay of hydrogen bonding and aromatic-packing interactions in producing lamellar, 2D lamellar, and columnar arrangements of complex cations in the crystalline state is discussed.
