Tetra-kis(pyridazine-κN)bis-(thio-cyanato-κN)nickel(II) pyridazine disolvate

摘要

The reaction of nickel(II) thio-cyanate with an excess of pyridazine leads to single crystals of the title compound, [Ni(NCS)2(C4H4N2)4]·2C4H4N2. The NiII cations are coordinated by two terminal N-bonded thio-cyanate anions (trans) and four pyridazine ligands in a slightly distorted octa-hedral geometry. The discrete complexes are arranged into layers parallel to the ab plane which are separated by additional non-coordinated pyridazine ligands.
