Abstract

Complexes of 2,2-cis [Rh2(N{C6H5}COCH3)4] bound to benzonitrile, ortho-tolunitrile, and meta-tolunitrile were synthesized and characterized using X-ray crystallography, IR spectroscopy, and proton NMR. The crystal structures of 2,2-cis [Rh2(N{C6H5}COCH3)4]•2NCC6H5, 2,2-cis [Rh2(N{C6H5}COCH3)4]•2NC{2-CH3}C6H4, and 2,2-cis [Rh2(N{C6H5}COCH3)4]•2NC{3-CH3}C6H4 were solved using a Rigaku Mercury375R/M CCD XtaLab Mini Diffractometer. The 2,2-cis [Rh2(N{C6H5}COCH3)4]•2NCC6H5 complex had unit cell dimensions of a=10.2115(7) Å, b=9.9667(7) Å, c=21.367(2) Å, and β=100.971(7)° with a P21/n space group. The 2,2-cis [Rh2(N{C6H5}COCH3)4]•2NC{2-CH3}C6H4 complex had unit cell dimensions of a=10.3625(8) Å, b=10.0489(7) Å, c=21.611(2) Å, and β=100.868(7)° with a P21/n space group. The 2,2-cis [Rh2(N{C6H5}COCH3)4]•2NC{3-CH3}C6H4 complex had unit cell dimensions of a=10.849(3) Å, b=11.530(3) Å, c=12.259(3) Å, α=117.562(8)°, β=103.061(7)°, and γ=101.562(7)° with a P-1 space group. Each rhodium atom had approximate octahedral coordination and was bound to another rhodium atom along with two equatorially bound nitrogens and two equatorially bound oxygens and one axially bound nitrogen that was a part of the nitrile.
