2D-supramolecular layers built of antiferromagnetically coupled [Cu(x-O2Nbz)2(denia)1(H2O)1]n 1D-polymers with R22(10) and R22(12) supramolecular synthons

Three unusual polymeric spiral-like complexes [Cu(O2Nbz)2(μ-denia)1(H2O)1]n that by H-bond formation between coordinated water and carboxylate groups form 2D-supramolecular layers have been studied. Their susceptibility maxima are about 6-7 K and the Bleaney-Bowers equation fits confirm that the spin-spin interaction pathways include hydrogen bonds.
