catena‐Poly­[[[(1,10‐phenanthroline‐κ2N,N′)­manganese(II)]‐μ‐l‐tartrato‐κ4O1,O2:O3,O4] hexahydrate]

The title compound, {[Mn(C₄H₄O₆)(C₁₂H₈N₂)]·6H₂O}_n, has a linear chain structure containing monomeric [Mn(C₄H₄O₆)(C₁₂H₈N₂)] repeat units. Each manganese ion is six‐coordinate, with the two phenanthroline N atoms [Mn—N = 2.229 (2) and 2.235 (2) Å] and four O atoms from two tartrate anions [Mn—O_COO = 2.1252 (19) and 2.1310 (19) Å, and Mn—O_OH = 2.2404 (19) and 2.2424 (19) Å] forming a seriously distorted octahedral coordination environment. Six water mol­ecules exist outside every repeat unit as solvate mol­ecules. Extensive hydrogen‐bonding interactions and π–π stacking of the phenanthroline moieties exist between the chains.
