摘要
A one-dimensional chain complex {Na[ZnL(H2O)2]}n was synthesized by sodium 2,2-dihydroxyl-malonate (Na2L?) and hydrate zinc perchlorate. The crystal belongs to the mono- clinic system, space group P21/n with a = 5.936(2), b = 7.203(3), c = 19.356(8) ? b = 95.264(6), V = 824.2(6) 3, Z = 4, C3H5NaO8Zn, Mr = 257.43, Dc = 2.075 g/cm3, F(000) = 512 and m = 3.045 mm-1. The structure was refined to R = 0.0381 and wR = 0.0766 for 1188 observed reflections (I > 2s(I)). In the complex the zinc(II) atom is coordinated to six oxygen atoms from two H2O mole- cules, two carboxylate groups, one ionized hydroxyl group and one hydroxyl group. By the coordi- nation of zinc(II) ions and bridging ligand 2-hydroxyl-2-hydroxylate-malonate trivalent anion the one-dimensional chain is constructed.
