| Abstract: | An X-ray—diffraction study is reported for two molecular complexes containing 3,4-diamino-1,2,5-oxadiazole as guest (G) with 18-crown-6 (18-C-6) andcis-anti-cis-dicyclohexano-18-crown-6 (DCH-6B) as host. Both complexes are of the polymeric-chain structure with the guest molecule bridging two crown neighbours. ComplexI: 18-C-6*G*H2O], 1 11, monoclinic,P21/n,a=8.171(1),b=15.042(2),c=16.209(6) Å,  =101.15(2)°, finalR-factor 0.068. ComplexII: DCH-6B*G], 11, monoclinicC2/c,a=21.212(4),b=9.380(2),c=13.049(3) Å, =108.61(3)°, finalR 0.047. |
