Diazido-bis[4,4,5,5-tetra-methyl-2-(1,3-thia-zol-2-yl)-2-imidazoline-1-oxyl-3-oxide-?O,N]manganese(II).

Project description:In the crystal structure of the title compound, [Mn(N(3))(2)(C(10)H(14)N(3)O(2)S)(2)], the Mn(II) atom exhibits a roughly octa-hedral coordination geometry. The Mn(II) atom lies on an inversion centre, thus the asymmetric unit comprises one half-mol-ecule. The metal center is six-coordinated by two azide anions and by two chelating 4,4,5,5-tetra-methyl-2-(1,3-thia-zol-2-yl)-2-imidazoline-1-oxyl-3-oxide nitronyl nitroxide radical ligands, leading to two six-membered chelate rings.
