Abstract
The title compound, an adduct of rhodium(II) benzoate [Rh2(bz)4] with pyrimidine (pym) and acetonitrile, [Rh2(bz)4-(pym)]2n·n[Rh2(bz)4(CH3CN)2]·2nCH3CN, was isolated, and the crystal structure was determined by the single-crystal X-ray diffraction method at 90 K. It crystallizes in the triclinic space group P1 with a = 10.728(2)Å, b = 15.002(3)Å, c = 15.860(3)Å, α = 68.321(3)°, β = 82.549(4)°, γ = 85.492(4)°, V = 2350.5(8)Å3, Dx = 1.692 g/cm3, and Z = 1. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0460 and 0.1074, respectively, for all 10430 independent reflections. The crystal contains zigzag chain molecules with an alternating arrangement of Rh2(bz)4 [Rh-Rh 2.3914(9), 2.3946(9)Å] and pym, diacetonitrile adduct molecules Rh2(bz)4(CH3CN)2 [Rh-Rh 2.3951(10)Å], and acetonitrile molecules.
