✦ Synopsis

The Zn atom of the title complex, [Zn(NCS)~2~(C~7~H~8~N~4~O)~2~(H~2~O)~2~] or [Zn(SCN)~2~(H-Pysc)~2~(H~2~O)~2~] [H-Pysc = N-aminocarbonyl-N′-(3-pyridylmethylene)hydrazine], derived from the condensation of pyridine-3-carbaldehyde and semicarbazone, is located at a crystallographic centre of inversion and is octahedrally coordinated by two thiocyanate anions, two aqua molecules and two molecules of the neutral Schiff base ligand H-Pysc. The Schiff base molecules act as monodentate ligands coordinating the metal through the pyridyl N atom, whereas the amide O and imine N atoms remain uncoordinated. The crystal packing is stabilized by intermolecular hydrogen bonds involving H-Pysc ligands, thiocyanate anions and water molecules.

In the title centrosymmetric dinuclear complex, [Ni 2 (NCS) 2 -(C 10 H 15 N 3 ) 2 ](ClO 4 ) 2 , each Ni II ion is pentacoordinated by the pyridine N, imine N, and amine N atoms of the Schiff base ligand, and by the terminal N and S atoms from two bridging thiocyanate ligands, forming a slightly dist
