A novel three-dimensional coordination polymer: poly[di-mu3-acetato-di-mu2-acetato-di-mu3-hydroxido-octa-mu3-triazolato-heptamanganese(II)].
The title compound, [Mn7(C2H2N3)8(C2H3O2)4(OH)2]n, is composed of centrosymmetric heptanuclear building units with the central Mn atom on an inversion center. In the building block, three Mn(II) ions are held together by one mu3-hydroxide group, two mu2-triazolate (trz) ligands and two mu2-acetate groups, forming an Mn3 cluster. Two Mn3 clusters are bridged by an Mn atom via two mu2-trz ligands and two mu2-O atoms from two acetate ions to construct a heptanuclear building block. The heptanuclear building units, lying parallel to each other along the b direction, form one-dimensional ladder-like chains and are further interlinked, resulting in a three-dimensional framework through Mn-N(trz) bonds.
