The crystal structure described by Mn(HCOO)2 crystallizes in the orthorhombic Pbcn space group. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form edge-sharing MnO6 octahedra. C(1) is bonded in a trigonal planar geometry to one H(1), one O(1), and one O(2) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Mn(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Mn(1) and one C(1) atom. is represented by the CIF card [CIF]
