cis‐Diaqua­[(E)‐2‐(2‐oxidobenzyl­idene­amino‐κ2N,O)­benzoato‐κO]copper(II): tubes built from O—H⋯O hydrogen‐bonding, π–π and C—H⋯π inter­actions

In the title compound, Cu(C₁₄H₉NO₃)(H₂O)₂], which crystallizes with Z = 18 in the space group R, pairs of complexes are linked into dimers by three O—H⋯O hydrogen bonds. Strong O—H⋯O hydrogen bonds link the dimers into one‐dimensional chains that further assemble into tubes through π–π and C—H⋯π inter­actions.
