- We synthesized three copper(II) complexes with two structurally related polydentate ligands,quinoline-4-carboxylic acid (quCOOH) and quinoxaline (qux). The structures of these complexes were determined using X-ray single crystal crystallography. Complex 1,[Cu(quCOO)(N3)(H2O)]n, has a 2-D polymeric structure through di-μ1,1 azido groups forming (Cu2N2) dimeric units and di-μN,O quinoline carboxylate bridging the binuclear copper units.[Cu(quCOO)(N3)(H2O)]n . 0.87MeOH, (2), has the same structure as 1 in addition to MeOH molecules separating the 2-D sheets of [Cu(quCOO)(N3)(H2O)]n. [Cu(qux)(NO3)2]n, (3), has nocoordinated azido groups, but the quinoxaline is a bidentate bridging ligand giving a 1-D chain,while the μO,O' chelating nitrato groups stabilize the chain structure by forming a square planarcoordination sphere around copper. IR and UV–Vis spectra of the complexes are in agreementwith the crystal structures.
