Hemipotassium hemirubidium digallium(III) manganese(II) tris(phos-phate) dihydrate.

ABSTRACT: The title manganese(II) substituted gallophosphate, K(0.5)Rb(0.5)[Ga(2)Mn(PO(4))(3)(H(2)O)(2)], features a three-dimensional network built of PO(4) tetra-hedra, GaO(5) trigonal bipyramids and MnO(6) octa-hedra. The Rb(I) and K(I) ions, which are disordered with respect to each other in a 1:1 ratio, occupy sites within the channels of the framework. The Rb(I)/K(I) and Mn(II) atoms occupy positions of 2 symmetry, as does one of the two P atoms. The Rb(I)/K(I) site is surrounded by six O atoms [2.996?(2)-3.178?(4)?Å] in an irregularly-shaped coordination environment. O-H?O hydrogen bonds between the water molecules and phosphate O atoms consolidate the crystal packing.

Dicobalt(II) lead(II) hydrogenphos-phate(V) phos-phate(V) hydroxide monohydrate.

Project description:The title compound, Co(2)Pb(HPO(4))(PO(4))OH·H(2)O, which was synthesized under hydro-thermal conditions, crystallizes in a new structure type. Except for two O atoms in general positions and two Co atoms on centres of symmetry, all other atoms in the asymmetric unit (1 Pb, 2 Co, 2 P, 8 O and 4 H) are located on mirror planes. The structure is built up from two infinite linear chains, viz.(1) (∞)[CoO(2/1)(H(2)O)(2/2)O(2/2)] and (1) (∞)[CoO(2/1)(OH)(2/2)O(2/2)], of edge-sharing CoO(6) octa-hedra running along [010]. Adjacent chains are linked to each other through PO(4) and PO(3)(OH) tetra-hedra, leading to the formation of layers parallel to (100). The three-dimensional framework is formed by stacking along [100] of adjacent layers that are held together by distorted PbO(8) polyhedra. Hydrogen bonds of the type O-H⋯O involving the water mol-ecule are very strong, while those O atoms involving the OH groups form weak bifurcated and trifurcated hydrogen bonds.

Tris(ethyl-enediamine)-cobalt(III) diformatodioxalatoindate(III) dihydrate.

Project description:In the cation of the title compound, [Co(C(2)H(8)N(2))(3)][In(C(2)O(4))(2)(CHO(2))(2)]·2H(2)O, the Co-N bond lengths lie in the range 1.960?(5)-1.997?(5)?Å. In the anion, the In(III) atom is coordin-ated by four O atoms from two oxalato ligands and two O atoms from two formato ligands in a distorted octa-hedral geometry. Inter-molecular O-H?O and N-H?O hydrogen bonds form an extensive hydrogen-bonding network, which link the cations, anions and water mol-ecules into three-dimensional structure.

Tris[tris-(1,10-phenanthroline-?N,N')iron(II)] dodeca-tungstoferrate dihydrate.

Project description:The title compound, [Fe(C(12)H(8)N(2))(3)](3)[FeW(12)O(40)]·2H(2)O, was prepared under hydro-thermal conditions. The discrete Keggin-type [FeW(12)O(40)](6-) heteropolyoxoanion has threefold symmetry, with the Fe(II) atom located on the threefold rotation axis. The central FeO(4) tetra-hedron in the anion shares its O atoms with four W(3)O(13) trinuclear units, each of which is made up of three edge-shared WO(6) octa-hedral units. The Fe(II) atom in the complex cation, viz [Fe(phen)(3)](2+) (phen is 1,10-phen-anthroline), shows a slightly distorted octa-hedral geometry defined by six N atoms from three phen ligands. The polyoxoanions pack together with the cations, with the disordered water mol-ecules located in voids; the site occupancy factor for each water O atom is 0.33.

Tris(ethyl-enediamine)manganese(II) sulfate.

Project description:In the title compound, [Mn(C(2)H(8)N(2))(3)]SO(4), the metal atom (site symmetry 3.2) is coordinated by six N atoms from three ethyl-enediamine (en) ligands in a slightly distorted octa-hedral geometry. The en ligands are generated from one half-mol-ecule in the asymmetric unit. The O atoms of the sulfate anion (S site symmetry 3.2) are disordered over four orientations in a 0.220 (12):0.210 (13):0.203 (14):0.10 (2) ratio, with one of the O atoms having site symmetry 3. In the crystal, the ions are connected by N-H⋯O hydrogen bonds, forming a three-dimensional network.
