| Abstract: | In the crystal structure of [(n-C4H9)4N]+·[NH2(C2N2S)NHCOO?]·NH2CSNC(NH2)2 (1), guanylthiourea molecules and 1,3,5-thiadiazole-5-amido-2-carbamate ions are joined together by intermolecular N–H…O, N–H…N, and weak N–H…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)4N]+·[NH2(C2N2S)NHCOO?]·NH2CSNC(NH2)2·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. |
