Catena-Poly[[[diaqua-bis[4-(diethyl-amino)benzoato-κO]manganese(II)] - μ - aqua] dihydrate]

In the crystal structure of the title complex, {[Mn(C₁₁H ₁₄NO₂)₂(H₂O)₃] ·2H₂O}_n , the two independent Mn^II atoms are located on a centre of symmetry and coordinated by two 4-(diethyl-amino) benzoate (DEAB) anions and two water mol-ecules in the basal plane while another water mol-ecule bridges the Mn atoms in the apical directions, forming polymeric chains. The dihedral angles between the carboxyl-ate groups and the adjacent benzene rings are 11.33 (13) and 10.90 (9)° and the benzene rings are oriented at a dihedral angle of 67.88 (6)°. The uncoordinated water mol-ecules link the carboxyl-ate groups and coordinated water mol-ecules via O - H⋯O hydrogen bonding. Weak C - H⋯π inter-actions are also found in the crystal structure.
