Tris(ethyl-enediamine-?(2)N,N')cadmium hexa-fluoridogermanate.

ABSTRACT: In the title compound, [Cd(C(2)H(8)N(2))(3)](GeF(6)), the Cd(II) atom, lying on a 32 symmetry site, is coordinated by six N atoms from three ethyl-enediamine (en) ligands in a distorted octa-hedral geometry. The Ge atom also lies on a 32 symmetry site and is coordinated by six F atoms. The en ligand has a twofold rotation axis passing through the mid-point of the C-C bond. The F atom is disordered over two sites with equal occupancy factors. In the crystal, the [Cd(en)(3)](2+) cations and [GeF(6)](2-) anions are connected through N-H?F hydrogen bonds, forming a three-dimensional supra-molecular network.

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

Project description:The structure of the title compound, [Co(II)(C(2)H(8)N(2))(3)]SO(4), the cobalt example of [M(C(2)H(8)N(2))(3)]SO(4), is reported. The Co and S atoms are located at the 2d and 2c Wyckoff sites (point symmetry 32), respectively. The Co atom is coordinated by six N atoms of three chelating ethyl-enediamine mol-ecules generated from half of the ethyl-enediamine mol-ecule in the asymmetric unit.

The H atoms of the ethyl-enediamine mol-ecules inter-act with the sulfate anions via inter-molecular N-H?O hydrogen-bonding inter-actions.

Bis[tris-(ethyl-enediamine-?N,N')cobalt(III)] octa-kis-?-(3)-oxido-hexa-deca-?(2)-oxido-tetra-deca-oxido-?(12)-tetra-oxo-silicato-octa-molybdenum(VI)hexa-vanadium(IV,V) hexa-hydrate.

Project description:The title compound, [Co(C(2)H(8)N(2))(3)](2)[SiMo(8)V(4)O(40)(VO)(2)]·6H(2)O, was prepared under hydro-thermal conditions. The asymmetric unit consists of a transition metal complex [Co(en)(3)](3+) cation (en is ethyl-enediamine), one half of an [SiMo(8)V(4)O(40)(VO)(2)](6-) heteropolyanion, two solvent water mol-ecules in general positions and two half-mol-ecules of water located on a mirror plane. In the complex cation, the Co(3+) ion is in a distorted octa-hedral coordination environment formed by six N atoms of the three chelating en ligands. One of the en ligands exhibits disorder of its aliphatic chain over two sets of sites of equal occupancy. The [SiMo(8)V(4)O(40)(VO)(2)](6-) heteropolyanion is a four-electron reduced bivanadyl-capped ?-Keggin-type molybdenum-vanadium-oxide cluster. In the crystal, it is located on a mirror plane, which results in disorder of the central tetra-hedral SiO(4) group: the O atoms of this group occupy two sets of sites related by a mirror plane. Furthermore, all of the eight ?(2)-oxide groups are also disordered over two sets of sites with equal occupancy. There are extensive inter-molecular N-H?O hydrogen bonds between the complex cations and inorganic polyoxidoanions, leading to a three-dimensional supra-molecular network.
