(1,4,7,10,13,16-Hexaoxacyclo-octa-deca-ne)dimethyl-indium(III) trifluoro-methane-sulfonate.

In the title compound, [In(CH(3))(2)(C(12)H(24)O(6))](CF(3)O(3)S), two of the In-O distances within the cation are significantly shorter than the other four. The In(III) atom is in a distorted hexa-gonal-bipyramidal coordination geometry in which the C-In-C angle is 175.44†(12)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
