Abstract The crystal structures of inclusion compounds of 4-aminobenzenesulfamidine (sulfaguanidine) (L) with two dicyclohexano-18-crown-6 (DCH-6) isomers A(cis-syn-cis) and B(cis-anti-cis) have been determined by X-ray methods. The complexes exhibit 1:2 host-guest ratios. In fact the complex of isomer A is formulated as [DCH-6A·[L]H2O]L (complexI), while that of isomerB is DCH-6 B L2 (complex I1). In the crystals, host and guests are connected by O-H...0 and N-H...O bonds.
