N2 - A novel mixed anion complex has been prepared in the course of crystal engineering studies of guanidinium organosulfonates. Bis(guanidinium) ethanesulfonate chloride, {[C(NH2)3]+}2CH3CH 2SO3-Cl-, assembles into a crystalline lattice which exhibits structural characteristics reminiscent of both of its monoanion counterparts guanidinium chloride and guanidinium ethanesulfonate. The structure nominally contains two-dimensional (001) hydrogen-bonded sheets resembling those found in guanidinium organosulfonates, but in which chloride ions replace half of the sulfonate ions. The (001) sheets consist of alternating guanidinium-sulfonate and guanidinium-chloride hydrogen-bonded ribbons, linked together by guanidinium-sulfonate and guanidinium-chloride hydrogen bonds. The presence of chloride ions in the (001) sheets expands this network to enable interweaving of a second hydrogen-bonded sheet, consisting only of guanidinium and chloride ions, orthogonal to the (001) sheets. The interweaving also is made possible by the isotropic nature of the chloride ion with respect to hydrogen bonding.
