In the crystal structure of the title complex, {[Mn(C(11)H(14)NO(2))(2)(H(2)O)(3)]·2H(2)O}(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.
在标题配合物{[Mn(C₁₁H₁₄NO₂)₂(H₂O)₃]·2H₂O}ₙ的晶体结构中，两个独立的Mn(II)原子位于对称中心，在基面由两个4-(二乙氨基)苯甲酸根（DEAB）阴离子和两个水分子配位，而另一个水分子在轴向桥连Mn原子，形成聚合物链。羧酸根基团与相邻苯环之间的二面角为11.33 (13)°和10.90 (9)°，苯环以67.88 (6)°的二面角取向。未配位的水分子通过O-H⋯O氢键连接羧酸根基团和配位水分子。在晶体结构中还发现了弱的C-H⋯π相互作用。
