| Sumario: | The crystal structures of Na2Cu(2,3-pydc)2.8H2O (1) and Cu(3,4-pydc).3.5H2O (2) (pydc = pyridinedicarboxylato) are presented. Compound (1) is monoclinic; space group (72/c, with a 21.274(1), b 6.114(1), c 17.136(1) Å, β 101.62(1)°, Z 4, Dc 1.776 g cm-3; compound (2) is also monoclinic, space group P21/c, with a 7.272(2), b 11.319(3), c 25.453(9) Å, β 90.58(1)°, Z 4, Dc 1.850 g cm-3. Their stereochemistries are analysed, and compared with other copper(n) pyridine-2,6-dicarboxylates. Ligand constraints are shown to determine the crystal structures and the magnetic properties. Thermal dependence of magnetic susceptibility data and t.g., d.t.g. and d.t.a. measurements are also presented. |
