Guanidinium alkynesulfonates with single-layer stacking motif: interlayer hydrogen bonding between sulfonate anions changes the orientation of the organosulfonate R group from "alternate side" to "same side".
Hydrolyses of HC[triple bond]CSO3SiMe3 (1) and CH3C[triple bond]CSO3SiMe3(2) lead to the formation of acetylenic sulfonic acids HC[triple bond]CSO3H.2.33H2O (3)and CH3C[triple bond]CSO3H.1.88H2O (4). These acids were reacted with guanidinium carbonate to yield [+C(NH2)3][HC[triple bond]CSO3] (5) and [+C(NH2)3][CH3C[triple bond]CSO3] (6). Compounds 1-6 were characterized by spectroscopic methods...
متن کامل2-Amino-5-trifluoromethyl-1,3,4-thiadiazole and a redetermination of 2-amino-1,3,4-thiadiazole, both at 120 K: chains of edge-fused R(2)(2)(8) and R(4)(4)(10) rings, and sheets of R(2)(2)(8) and R(6)(6)(20) rings.
Molecules of 2-amino-5-trifluoromethyl-1,3,4-thiadiazole, C3H2F3N3S, are linked by two independent N-H...N hydrogen bonds into sheets of alternating R(2)(2)(8) and R(6)(6)(20) rings, while the molecules of the unsubstituted 2-amino-1,3,4-thiadiazole, C2H3N3S, are linked, again by two independent N-H...N hydrogen bonds, but into chains of edge-fused R(2)(2)(8) and R(4)(4)(10) rings.

In the title compound, C(26)H(18)N(2)O(3), the maximum deviations from planarity for the tetra-hydro-1H-naphtho-[2,3-c]pyrrole and indoline rings systems are 0.091 (1) and 0.012 (2) Å, respectively. These ring systems make a dihedral angle of 89.95 (6)° with each other and they make dihedral angles of 73.42 (8) and 71.28 (9)°, respectively, with the benzene ring. In the crystal, inversion dimer...

The title compound, CH(6)N(3) (+)·C(7)H(4)NO(4) (-), an anhydrous guanidinium salt, shows a N-H⋯O hydrogen-bond network in which the guanidinium cation is involved in three cyclic R(2) (1)(6) hydrogen-bonding associations with separate carboxyl-ate O-atom acceptors. Further peripheral associations include a cyclic R(1) (2)(4) cation-anion inter-action, forming inter-linked undulating sheets in ...

The title acyl-hydrazone derivative, C17H19N3O3S, containing an amino acid moiety and electron-donating substituents attached to both the phenyl rings, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The mol-ecules are bent at the S atom, with C-SO2-NH-CH2 torsion angles of -67.3 (2) and 67.7 (3)° in mol-ecules A and B, respectively. Further, the dihedral angles b...
