Tris(bis[N-(2-aminoethyl)-1,2-ethanediamine-kappa3N]-nickell(II)) bis(tetrathioantimonate).

Yellow crystals of [Ni(deta)2]3[SbS4]2 (deta is diethylenetriamine, C4H13N3) were synthesized under solvothermal conditions by reacting elemental Ni, Sb and S in a solution of diethylenetriamine. The structure is composed of tetrahedral [SbS4]3- anions in general positions and octahedral [Ni(deta)2]2+ cations located at centres of inversion. In the crystal structure, the anions and cations are stacked in the direction of the a axis in a pseudo-hexagonal arrangement.

RbCu2VS4.

The reaction of Cu and V in a Rb(2)S(5) melt yields black crystals of rubidium dicopper vanadium tetrasulfide, RbCu(2)VS(4). The structure is comprised of [Cu(2)VS(4)](-) layers within the (010) plane which are separated by Rb(+) cations. The layers consist of a network of edge- and corner-sharing [VS(4)] and [CuS(4)] tetrahedra parallel to (010). The optical band gap was determined as 1.45 eV.

Bis

The title double salt, [Ni(C(2)H(8)N(2))(3)](2)(SbS(4))(NO(3)), was crystallized under solvothermal conditions. Hydrogen bonds between the SbS(4)(3-) anions (at four sites) and the [Ni(en)(3)](2+) (en = ethylenediamine) cations (at two sites) form a three-dimensional network. The NO(3)(-) anion is disordered over four sites. The cation lies on a twofold rotation axis and the SbS(4)(3-) anion on a -4 axis.
