Synthesis, X-ray crystal structure and thermal decomposition of two peroxovanadium complexes with coordinated ammonia molecules: [{VO(O-2)2(NH3)}(2){[mu-Cu(NH3)(4)}] and [Zn(NH3)(4)][VO(O-2)(2)(NH3)](2)

Original language description

The compounds [{VO(O-2)(2)(NH3)}(2){mu-Cu(NH3)(4)}] (1) and [Zn(NH3)(4)][VO(O-2)(2)(NH3)](2) (2) were prepared and characterized by elemental analysis and infrared spectra. The single crystal X-ray study revealed that the structure of 1 consists of trinuclear complex molecules [(NH3)OV(O-2)(2){mu-Cu(NH3)(4)}(O-2)(2)VO(NH3)] with a rare heterobimetalic peroxo bridge: copper(II)-peroxo ligand-vanadium(V). The structure of 2 is composed of tetraamminezinc(II) cations and ammineoxodiperoxovanadate(V) anions. In course of thermal decomposition of 1 performed up to 620 degrees C, the following intermediate products: [Cu(NH3)(2)(VO3)(2)], and subsequently a mixture of V2O5 with monoclinic beta-Cu2V2O7, were gradually formed. The final product of decompositionis Cu(Vo(3))(2). The thermal decomposition of 2 is a two-step process. In the first stage, [Zn(NH3)3(VO3)2] as supposed intermediate was formed, which transformed at higher temperatures by release of ammonia molecules to the monoclinic m

Czech description

Sloučeniny [{VO(O-2)(2)(NH3)}(2){mu-Cu(NH3)(4)}] (1) a [Zn(NH3)(4)][VO(O-2)(2)(NH3)](2) (2) byly po přípravě charakterizovány elementár. analýzou a IČ spektry. RTG. krystalografií bylo zjištěno, že se struktura 1 skládá z 3-jader. komplexu [(NH3)OV(O-2)(2){mu-Cu(NH3)(4)}(O-2)(2)VO(NH3)] se vzácným bimetalickým peroxo můstkem Cu(II)-peroxoligand-V(V). Struktura 2 se skládá z tetraaminozinečnatých kationtů a aminooxodieroxo(V) aniontů.
