Aquabis(4-methylbenzenesulfonato-[kappa]O)([eta]5-pentamethylcyclopentadienyl)rhodium(III) monohydrate

C. P. Roy, P. M. Boyer and J. S. Merola

Abstract: The title half-sandwich rhodium(III) complex, [Rh(C10H15)(C7H7O3S)2(H2O)]·H2O, consists of a [pi]-bonded pentamethylcyclopentadienyl group, two [sigma]-bonded tosylate groups and an aqua ligand. The structure displays both inter- and intramolecular O-H...O hydrogen bonding. The intermolecular hydrogen bonding results in an extended helical chain along a 21 screw axis parallel to c, due to hydrogen bonding from the coordinating water ligand to the lattice water molecule and then to a sulfonate O atom of a different asymmetric unit.
