چکیده
The title salt, [Ni(C3H2NS2)(C12H8N2)2]PF6·1.5C4H8O2, was the unexpected product on making an attempt to prepare an [Ni(2-mercapto-thia-zol-ate)(1,10-phenanthroline)]+ complex by reaction of [NiCl2(1,10-phen-an-throline)] with 2-mercapto-thia-zolate. In the resulting complex, the 2-mercapto-thia-zolate anion acts as a chelating ligand, which coordinates to the NiII ion with the thia-zolyl N and thiol-ate S atoms. In the crystal, π-π stacking inter-actions between the coordinating 1,10-phenanthroline mol-ecules of adjacent complexes result in a zigzag chain running parallel to the c axis. Weak C-H⋯X (X = O, F) hydrogen-bonding inter-actions between the chains and 1,4-dioxane solvent mol-ecules and PF6- counter-anions lead to the formation of sheets parallel to the ac plane.
