Crystal structure of catena-poly[[copper(II)-μ2-salicylato-[diaquacopper(II)]-μ2-salicylato] dihydrate]
The title compound, {[Cu2(C7H4O3)2(H2O)2]·2H2O} n , contains two copper(II) cations in special positions (one on a twofold rotation axis and one on an inversion centre) and the the salicylate ligand in its dianionic form. By four- and six-coordinate metal coordination, chains are formed parallel to [001], which are extended by O-H⋯O hydrogen bonding into sheets extending parallel to (100). Thes...
متن کاملCrystal structure of [triaqua(salicylato)(nicotinamide)zinc(II)] salicylate.
vitamin leads to a loss of copper from the body, known as pellagra disease. The nicotinamide derivative, N,Ndiethylnicotinamide (DENA), is an important respiratory stimulant. A structure determination of the title compound was undertaken in order to determine the ligand properties of NA and salicylate ligands. The title compound was prepared from the reaction of Zn(2HO-C6H5COO)2·8(H2O) (1.46 g,...
متن کاملCrystal structure of poly[[di-μ3-acetato-tetraaquabis(μ2-cyclohexane-1,4-dicarboxylato)dilanthanum(III)] dihydrate]
The title compound, {[La2(CH3COO)2(C8H10O4)2(H2O)4]·2H2O} n or [La2(ac)2(e,a-cis-1,4-chdc)2(H2O)4]·2H2O, where ac is acetate and 1,4-chdc is cyclo-hexane-1,4-di-carboxyl-ate anion, is a binuclear lanthanum(III) complex. Each metal atom is deca-coordinated by four O atoms from two distinct 1,4-chdc2- ligands, four O atoms from three acetate groups and two O atoms from coordinated water mol-ecule...
متن کاملCrystal structure of a polymeric calcium levulinate dihydrate: catena-poly[[diaquacalcium]-bis(μ2-4-oxobutanoato)]
In the title calcium levulinate complex, [Ca(C5H7O3)2(H2O)2] n , the Ca(2+) ion lies on a twofold rotation axis and is octa-coordinated by two aqua ligands and six O atoms from four symmetry-related carboxyl-ate ligands, giving a distorted square-anti-prismatic coordination stereochemistry [Ca-O bond-length range = 2.355 (1)-2.599 (1) Å]. The levulinate ligands act both in a bidentate carboxyl ...
متن کاملCrystal structure of catena-poly[[cadmium(II)-di-μ2-bromido-μ2-l-proline-κ2 O:O′] monohydrate]
In the title coordination polymer, {[CdBr2(C5H9NO2)]·H2O} n , the Cd(II) ion is coordinated by four bromido ligands and two carboxyl-ate oxygen atoms of two symmetry-related proline ligands, which exist in a zwitterionic form, in a distorted octa-hedral geometry. There is an intra-molecular N-H⋯O hydrogen bond between the amino group and the carboxyl-ate fragment. Each coordinating ligand bridg...
