Crystal structure, synthesis and thermal properties of bis(acetonitrile-κN)bis(4-benzoylpyridine-κN)bis(isothiocyanato-κN)nickel(II)

Abstract

In the crystal structure of the title com­pound, the NiII cations are octa­hedrally coordinated into discrete solvate com­plexes, that upon heating loses the aceto­nitrile ligands and transforms into an unknown modification of [Ni(NCS)2(4-benzoyl­pyridine)2].

Synthesis, characterization and thermal behaviour of solid phases in the quasi-ternary system Mg(SCN)2–H2O–THF

“…Moreover, magnesium is very similar to nickel in terms of ionic radius and preference for an octahedral coordination, 56 so exploring SCN-THF complexes appears to be an excellent opportunity to further expand the rich coordination chemistry of nickel(II) thiocyanates. [57][58][59][60] Indeed, similar M II (SCN)2 • 4 THF complexes with M = Ni, V and a M II (SCN)2 • 2 THF phase with M = Co have been found, 61 but the thermal behaviour and the polymorphism have not been investigated yet.…”
