and single-crystal X-ray diffraction. The Ni atom in (1) is four-coordinated in a square planar configuration, with three donor atoms of L1 and one nitrogen atom of thiocyanate ligand. The Ni atom in (2) is six-coordinated in an octahedral configuration, with six donor atoms from two L2 ligands. The relationship between the ligands and the final structures of the complexes is discussed.
