Crystal structure of bis­(aceto­phenone 4-benzoyl­thio­semicarbazonato-κ(2) N (1),S)nickel(II)

In the asymmetric unit of the title complex, [Ni(C(16)H(14)N(3)OS)(2)], the nickel ion is tetra­coordinated in a distorted square-planar geometry by two independent mol­ecules of the ligand which act as mononegative bidentate N,S-donors and form two five-membered chelate rings. The ligands are in trans (E) conformations with respect to the C=N bonds. The close approach of hydrogen atoms to the Ni(2+) atom suggests anagostic inter­actions (Ni⋯H—C) are present. The crystal structure is built up by a network of two C—H⋯O inter­actions. One of the inter­actions forms inversion dimers and the other links the mol­ecules into infinite chains parallel to [100]. In addition, a weak C—H⋯π inter­action is also present.
