Poly[tetramethylammonium [tri-μ2-formato-κ6O:O′-manganate(II)]]

Abstract

In the title compound, {(C4H12N)[Mn(HCO2)3]}n, the MnII atom lies on an inversion centre and is coordinated by O-atom donors from the three double-bridging formate ligands, one of which lies across a crystallographic mirror plane, giving a slightly distorted octahedral coordination sphere. A three-dimensional NaCl-type framework is generated in which the tetramethylammonium cations, which lie across mirror planes and occupy the cavities in the polymer structure, form weak C—H...O hydrogen bonds with the formate ligands.
