Aqua­(pyridine-κN)(N-salicylideneglycinato-κ³N,O,O′)copper(II)

In both of the two independent mol­ecules of the title compound, [Cu(C₉H₇NO₃)(C₅H₅N)(H₂O)], the copper atom is in a square-pyramidal coordination with the apical site occupied by water. The two mol­ecules are related by a non-crystallographic center of inversion. Hydrogen bonds link symmetry-equivalent mol­ecules into zigzag chains that run along the a axis of the ortho­rhom­bic unit cell.

N,N′-Bis(2-nitro­benzylidene)ethyl­ene­diamine

The mol­ecule of the title compound, C₆H₁₄N₄O₄, possesses a crystallographically imposed centre of symmetry. In the crystal packing, the mol­ecules are linked via weak inter­molecular C—H...O hydrogen bonds into a sheet-like structure parallel to the (10) plane.
