Rubidium(I) monensinate dihydrate

In the title complex, [Rb (C36H61O11)]center dot 2H(2)O, the Rb+ cation is coordinated by seven O atoms of monensin. Rb-O distances range from 2.7870 (17) to 3.1429 (17) angstrom. Both O atoms of the carboxylate group are involved in the coordination of Rb. The structure displays inter- and intramolecular O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen-bonding interactions
