The synthesis and crystallographic characterization of two copper salt complexes of ditopic ligand is examined. The result shows that ligand L can chelate to both the cation and anion of a transition metal salt. The copper ligand bond lengths in the two complexes lie within the usual ranges. A third hydrogen bond involves the other L ligand from a symmetry related complex molecule, which associates with the anion in monodentate fashion through its NH2 group. The functionalization of the amine or pyrazole moieties in L with additional hydrogen bond donors and /or hydrophobic substituents leads to a variety of new ditopic ligand geometries.
