Abstract

A complex compound [(NH3)6Rh2(μ-CO3)(μ-OH)2](NO3)2·H2O has been obtained and structurally characterized. Crystal data: a = 7.9103(16) Å, b = 9.606(2) Å, c = 11.283(2) Å, α = 103.206(4)°, β = = 110.045(4)°, γ = 93.890(5)°, space group P-1, Z = 2, dx = 2.335 g/cm3. The crystal structure is a packing of dimeric complex rhodium cations [Rh2(μ-OH)2(μ-CO3)(NH3)6]2+, nitrate anions, and crystallization water molecules joined by a system of hydrogen bonds. The compound has been investigated with IR spectroscopy and powder X-ray diffraction. The isolated crystalline phase is poorly soluble in water.
