In the title coordination polymer, catena-poly[[[triaqua-europium(III)]-bis-(μ-1H,3H-benzimidazol-3-ium-5,6-dicarb-oxyl-ato-κ(3)O(5),O(5'):O(6))-[triaqua-europium(III)]-di-μ-sulfato-κ(3)O:O,O';κ(3)O,O':O'] hexahydrate], [Eu(2)(C(9)H(5)N(2)O(4))(2)(SO(4))(2)(H(2)O)(6)]·6H(2)O}(n), the 1H,3H-benzimidazol-3-ium-5,6-dicarb-oxy-l-ate ligand is protonated at the(More)
In the title coordination polymer, [Ag(C(14)H(8)NO(2))](n), the Ag(I) cation is coordinated by two O atoms and one N atom from two symmetry-related acridine-9-carboxyl-ate ligands in a distorted trigonal-planar geometry. The metal atoms are connected by the ligands to form chains running parallel to the b axis. π-π stacking inter-actions(More)
In the title complex, {[Dy(C(6)H(4)NO(3))(C(2)O(4))(H(2)O)]·H(2)O}(n), the Dy(III) ion is coordinated by seven O atoms from two 2-oxidopyridinium-3-carboxylate ligands, two oxalate ligands and one water mol-ecule, displaying a distorted bicapped trigonal-prismatic geometry. The carboxyl-ate groups of the 2-oxidopyridinium-3-carboxylate and oxalate ligands(More)
The asymmetric unit of the title complex, {[AgEr(C(5)H(3)N(2)O(2))(2)(C(2)O(4))]·H(2)O}(n), contains one Er(III) atom, one Ag(I) atom, two pyrazine-2-carboxyl-ate (pyc) ligands, two half oxalate ligands (each lying on an inversion center) and one uncoordinated water mol-ecule. The Er(III) atom is coordinated by two O atoms and two N atoms from two pyc(More)
In the title complex, {[Ag(2)Nd(C(6)H(4)NO(2))(4)(H(2)O)(2)]NO(3)·H(2)O}(n), the Nd(III) ion is coordinated by eight O atoms from six isonicotinate ligands and two water mol-ecules in a distorted square anti-prismatic geometry. Each Ag(I) ion is coordinated by two N atoms from two different isonicotinate ligands. The crystal structure exhibits a(More)
