Heterometallic copper(II)-lead(II), nickel(II)-lead(II) and copper(II)-indium(III) compounds derived from an acyclic double-compartment Schiff base ligand

This work deals with the syntheses, characterization and crystal structures of four compounds of composition [NiIILOEt-pn(H2O)2PbIIBr2], [NiIILOEt-pn(H2O)2PbII(NO3)2], [{CuIILOEt-pn(μ-Br)PbII}2(μ-Br)2] and [{CuII(NO3)LOEt-pnInIII(NO3)}2(μ-OH)2], where H2LOEt-pn is N,N′-propanebis(3-ethoxysalicylaldimine). Interestingly, indium(III) is used for the first time here as a second metal ion in the family of numerous 3d-second metal ion systems derived from acyclic Schiff base ligands.
