Variation in crystallization conditions allows the isolation of trimeric as well as dimeric and monomeric forms of [(alkyl isocyanide)4RhI]+
Abstract
Trimeric green [(i-PrNC)12RhI3]Cl3·4.5H2O, monomeric [(C6H11NC)4RhI](BPh4) and [(i-PrNC)4RhI](BPh4) (both yellow), and red, dimeric [(C6H11NC)8RhI2]Cl2·0.5C6H6·2H2O have been crystallized.
