Transition metal complexes with thiosemicarbazide-based ligands. XLII.1 Bis(S-methylisothiosemicarbazido-N1,N4)bis(pyrazole-N 2)nickel(II) diiodide
Résumé
In the title compound, [Ni(C2H7N3S)2(C3H4N2)2]I2, the NiII ion assumes a centrosymmetric distorted octahedral geometry. The two molecules of S-methylisothiosemicarbazide are coordinated as bidentate ligands via the terminal N atoms, forming five-membered chelate rings. The I atoms are approximately in the equatorial plane of the chelate rings at a similar distance from both. The five-membered chelate rings are almost planar and exhibit flattened envelope conformations. There is a weak intermolecular interaction between the lone pair of electrons of the S atom and the center of the pyrazole ring.
