چکیده
The reaction of Ni(II) acetate tetra-hydrate with the ligand 4-phenyl-2-(1,2,3,4-tetra-hydro-naphthalen-1-yl-idene)hydrazinecarbo-thio-amide in a 2:1 molar ratio yielded the title compound, [Ni(C16H16N3S)2]·2C4H8O·H2O. The deprotonated ligands act as N,S-donors, forming five-membered metallacycles with the metal ion exhibiting a cis coordination mode unusual for thio-semicarbazone complexes. The Ni(II) ion is four-coordinated in a tetra-hedrally distorted square-planar geometry. Trans-arranged anagostic C-H⋯Ni inter-actions are observed. In the crystal, the complex mol-ecules are linked by water mol-ecules through N-H⋯O and O-H⋯S hydrogen-bonding inter-actions into centrosymmetric dimers stacked along the c axis, forming rings of graph-set R 4 (4)(12). Classical O-H⋯O hydrogen bonds involving the water and tetra-hydro-furan solvent mol-ecules as well as weak C-H⋯π inter-actions are also present.

In the title compound, C22H19N3O3S, the six-membered ring of the 1,2,3,4-tetra-hydro-naphthalene ring system adopts an envelope conformation with the central CH2 C atom as the flap. The mol-ecular conformation is stabilized by an S⋯O contact, forming a pseudo-five-membered ring. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds into chains propagating along [102].
