The title coordination polymer, [Zn(C6H4NO3)2] n , was prepared under hydro-thermal conditions by the reaction of zinc nitrate with 5-hy-droxy-nicotinic acid in the presence of malonic acid. In the structure, the Zn(II) ion is coordinated by two carboxyl-ate O atoms and two pyridine N atoms of four 5-hy-droxy-nicotinate ligands in a distorted tetra-hedral(More)
In the title compound, [Eu2(C6H5NO3)2(C2O4)3(H2O)4] n , the Eu(III) atom is bonded to one O atom from a monodentate 5-hy-droxy-pyridin-1-ium-3-carboxyl-ate ligand, six O atoms from three oxalate ligands and two water mol-ecules, exhibiting a highly distorted tricapped trigonal geometry. Three independent oxalate ligands, each lying on an inversion center,(More)
In the title compound, {[Ho(2)(C(6)H(4)NO(3))(2)(C(2)O(4))(2)(H(2)O)(2)]·2H(2)O}(n), the Ho(III) atom is coordinated by three O atoms from three 5-hy-droxy-nicotinate ligands, four O atoms from two oxalate ligands, each lying on an inversion center, and one water mol-ecule in a distorted square-anti-prismatic geometry. The 5-hy-droxy-nicotinate ligand is(More)
