Poly[methyl­ammonium tri-μ2-formato-κ6 O: O′-zinc(II)].

The structure of the polymeric title compound, {(CH6N)[Zn(CHO2)3]} n, consists of a three-dimensional anionic zinc formate network charge-compensated by methyl­ammonium cations. The Zn atom (site symmetry ) adopts a slightly distorted octa­hedral geometry arising from O atoms from six different formate anions. One complete formate ion is generated by mirror symmetry, and the C and N atoms of the organic cation lie on a mirror plane. [ABSTRACT FROM AUTHOR]
