cis‐Diaqua­bis[(E)‐4‐(2‐hydroxy­benzyl­idene­amino)benzoato‐κ2O,O′]cadmium(II): two‐dimensional layers built from strong O—H⋯O hydrogen bonding in the coordination sphere

In the title compound, [Cd(C 14 H 10 NO 3 ) 2 (H 2 O) 2 ], which crystallizes with Z = 4 in the space group C2c, the Cd atom is located on a twofold rotation axis and coordinated by six O atoms from two water molecules and two carboxylate groups of two planar 4-(2-hydroxybenzylideneamino)benzoate ligands, with a dihedral angle of 85.6 (1)° between them. Strong O-H···O hydrogen bonding in the coordination sphere, together with π-π stacking interactions, assemble the molecules into two-dimensional layers.
