Synthesis and structure of three molecular arylindium phosphinates

Reported here are the syntheses and molecular structures of three novel arylindium phosphinates, [(2,6-Mes₂C₆H₃In)₂(OH)₂(O₂PMe₂)₂] (1), [(2,6-Mes₂C₆H₃In)₂(OH) (O₂PPh₂)₃] (2), and [(2,6-Mes₂C₆H₃In)(O₂PMe₅C₃H)₂(H₂O)₂] (3), which were obtained by condensation reaction of the m-terphenylindium dihydroxide [(2,6-Mes₂C₆H₃In(OH)₂]₄ with dimethylphosphinic acid, diphenylphosphinic acid, and ,2,3,4,4-pentamethylphosphetanic acid, respectively.
