摘要

Treatment of [RhCl(CO)(PPh3)2] with an equivalent of (E)-2-((2-(methylsulfinylphenyl)imino)methyl)phenol (HL1) or (E)-4-chloro-2-((2-(methylsulfinylphenyl)imino)methyl)phenol (HL2) in ethanol at reflux afforded two rhodium(III) amido complexes of [RhCl(L1)(LNS)] (1) and [RhCl(L2)(LNS)] (2) (HLNS = 2-(methylsulfinyl)aniline), respectively. The molecular structures of the two compounds were determined by single-crystal X-ray diffraction. Compounds 1 and 2 both crystallize in the monoclinic space group P21/n with a = 7.1735(3) Å, b = 26.0466(12) Å, c = 11.2288(6) Å, β = 95.868(3)° and Z = 4 for 1, and a = 7.3734(4) Å, b = 26.6522(12) Å, c = 11.1598(4) Å, β = 95.884(3)°, and Z = 4 for 2.
