title: catena-Poly[[[aqua-(formato-κO)(1,10-phenanthroline-κN,N')manganese(II)]-μ-formato-κO:O'] monohydrate].
abstract: The title compound, {[Mn(HCOO)(2)(C(12)H(8)N(2))(H(2)O)]·H(2)O}(n), consists of polymeric chains of the complex [Mn(HCOO)(2)(phen)(H(2)O)](∞) (phen is 1,10-phenanthroline) with solvent water mol-ecules. The chains contain six-coordinate Mn(II) ions bridged by formate anions. They are further extended into a three-dimensional network via O-H⋯O hydrogen-bonding inter-actions and inter-chain π-π stacking inter-actions, with a centroid-centroid distance of 3.679 (4) Å.
