Effect of N-donor ancillary ligands on structural and magnetic properties of oxalate copper(II) complexes

摘要

Through varying the auxiliary N-donor ligands under similar synthetic conditions nine new compounds: [Cu(C2O4)(pz)]_n (1), [Cu(C2O4)(apz)2l_n-(3H2O)_n (2), [Cu2(n-C2O4)2(H2O)2(ampz)4] (3), [Cu(C2O4)(mpz)2]_n (4), [Cu(C2O4)(aind)2]_n (5), [Cu2(C2O4)2(bpzm)2]_n-(3.5H2O)_n (6), [Cu{C2O4)(ampy)(H2O)]_n (7) {[Cu2(n-C2O4)(aepy)2]-[Cu(C2O4)2(H2O)2]}_n-(2H2O)_n (8) and [Cu4(u-C2O4)3(aepy)4
