The stepwise reaction of [2,6-Mes(2)C(6)H(3)In(OH)(2)](4) with carbon dioxide and ethylene glycol proceeded with the formation of (2,6-Mes(2)C(6)H(3)In)(4)(CO3)(2)(OH)(4)(H2O)(2) (1) and (2,6-Mes(2)C(6)H(3)In)(4)(OCH2CH2O)(2)(OH)(4) (2), respectively, and eventually produced (2,6-Mes(2)C(6)H(3)In)(4)(CO3)(2)(OCH2CH2OH)(2)(OH)(2) (3). Attempts to liberate ethylene carbonate upon heating of 3 were unsuccessful.
