Hexa-kis-{[1-(dimethyl-amino)-propyl-idene]oxidanium} bis-(dodeca-molybdo-phosphate) N,N-dimethyl-propionamide penta-solvate.

Abstract

In the asymmetric unit of the title salt, (C5H12NO)6[PMo12O40]2·5C5H11NO, there are two independent α-Keggin-type [PMo12O40]3− polyoxidoanions, which show characteristic features with respect to bond lengths and angles. One of the [CH3CH2C(=OH)N(CH3)2]+ cations is hydrogen bonded to the neighboring polyoxidoanion through a C=O—H⋯Obridge hydrogen bond. The organic mol­ecules and the remaining organic cations form [(C5H11NO)2H]+ mol­ecule–cation pairs, two of which lie about inversion centers, through O—H⋯O hydrogen bonds.
