Two new glaserite-type orthovanadates: RbKDy(VO) and CsKGd(VO).

The crystal structures of dirubidium potassium dysprosium bis-(vanadate), RbKDy(VO), and caesium potassium gadolinium bis-(vanadate), CsKGd(VO), were solved from single-crystal X-ray diffraction data. Both compounds, synthesized by the reactive flux method, crystallize in the space group 1 with the glaserite structure type. VO tetra-hedra are linked to DyO or GdO octa-hedra by common vertices to form sheets stacking along the axis.

Synthesis and structure of a new copper(II) complex with 3,4'-bi-1,2,4-triazolate.

The salt diaquo-diammine-bis(3,4'-bi-1,2,4-triazolate) copper(II) of the formula [Cu(bTA-)2(NH3)2(H2O)2] has been synthesized and structurally characterized by X-ray single crystal diffraction analysis. This complex adopts a monomeric structure. This monomer crystallizes in the triclinic system, space group P1 with a=5.
