Synthesis and structure of three molecular arylindium phosphinates

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