AbstractIn the crystal structure of [(n-C4H9)(4)N](+)center dot[NH2(C2N2S)NHCOO-]center dot NH2CSNC(NH2)(2) (1), guanylthiourea molecules and 1,3,5-thiadiazole-5-amido-2-carbamate ions are joined together by intermolecular N-HaEuro broken vertical bar O, N-HaEuro broken vertical bar N, and weak N-HaEuro broken vertical bar S hydrogen bonds to generate stacked host layers corresponding to the (110) family of planes, between which the tetra-n-butylammonium guest cations are orderly arranged in a sandwich-like manner. In the crystal structure of [(n-C3H7)(4)N](+)center dot[NH2(C2N2S)NHCOO-]center dot NH2CSNC(NH2)(2)center dot H2O (2), the tetrapropyl ammonium cations are stacked within channels each composed of hydrogen bonded ribbons of guanylthiourea molecules, 1,3,5-thiadiazole-5-amido-2-carbamate ions and water molecules.
