Novel three-dimensional coordination polymers based on [Mo 6Se8(CN)6]7- anions and Mn 2+ Cations

Abstract

Three novel coordination polymers K5[MnMo6Se 8(CN)6] • 8H2O (1), (Me4N) 4[{Mn(H2O)2}1.5Mo6Se 8(CN)6] • 4H2O (2), and K 3[{Mn2(H2O)4}Mo6Se 8(CN)6] • 7H2O (3) have been synthesized by layering of a methanol solution of [Mn(salen)]CH3COO (salen-N,N′-bis(salicylidene)ethylenediamine) on an aqueous solution of K7[Mo6Se8(CN)6] • 8H 2O. The compounds have been characterized by single-crystal X-ray diffraction analysis. All structures are based on negatively charged porous polymer frameworks where CN groups of [Mo6Se8(CN) 6]7- cluster complexes are coordinated to Mn2+ cations. Cavities in the frameworks are filled by additional cations and solvate water molecules. © 2008 Springer Science+Business Media, LLC.
