Abstract

The title salt, [Zn(C10H7NOS)2(H2O)2](BF4)2, crystallizes isotypically with the CoII analog in the monoclinic space group P21/n. In the com-plex cation, the central ZnII atom (site symmetry 1) has a pseudo-octa-hedral coordination environment with bonding to pyridyl N [2.0624 (18) Å] and carbonyl O [2.1030 (13) Å] atoms from the 2-thienyl 2-pyridyl ketone ligands. The remaining bonds are to water mol-ecules [2.1598 (16) Å], which form an O-H⋯F hy-dro-gen-bonded layer with BF4 - counter-ions.
