A Plausible Formation Mechanism of Polyoxoperoxomolybdates With Variable Structures.

The weak bands around 1100 cm SP -1 sp can be assigned to I v i (O-O) vibrations for the compounds containing peroxo ligands (1095, 1049 cm SP -1 sp for B Cs-1 b , 1093, 1026 cm SP -1 sp for B Rb-1 b , 1078, 1024 cm SP -1 sp for B Cs-2 b , and 1078, 1026 cm SP -1 sp for B Cs-3 b ). The absorption bands near 880 cm SP -1 sp are attributed to I v i (Mo-O) vibrations (894 cm SP -1 sp for B Cs-0 b , 877 cm SP -1 sp for B Rb-0 b , 893 cm SP -1 sp for B Cs-1 b , 881 cm SP -1 sp for B Rb-1 b , 877 cm SP -1 sp for B Cs-2 b , and 875 cm SP -1 sp for B Cs-3 b ). B Cs-1 b and B Rb-1 b initially lose water and decompose to A SB 2 sb Mo SB 3 sb O SB 10 sb (A = Cs or Rb) by losing O SB 2 sb by 600°C, calculated (found): B Cs-1 b ; 6.5% (6.3%), B Rb-1 b ; 10.3% (10.7%). However, final reaction products were identified to be B Cs-0 b (0 mL of H SB 2 sb O SB 2 sb ), B Cs-1 b (~0.3 mL of 30% H SB 2 sb O SB 2 sb ), or B Cs-2 b (~0.6 mL of 30% H SB 2 sb O SB 2 sb ) depending on the added H SB 2 sb O SB 2 sb .
