Abstract

In the title complex, [Cu(C7H5O3)2(C21H18N4O)2]·2H2O, the CuII atom is located on a centre of inversion and exists in a tetra­gonally distorted octahedral geometry with a CuN4O2 chromophore. The intra­molecular O—H⋯O hydrogen bond is highly strained due to the mol­ecular geometry and, as a result, is much shorter than expected. Inter­molecular C—H⋯O and C—H⋯O inter­actions are also observed.
