Project description:In the title compound, C22H19N4S(+)·Br(-)·H2O, the dihedral angles between the phenyl groups and the mean plane of the thia-zolyl-idene ring are 34.69 (13) and 64.27 (13)°, respectively, while that between the thia-zolyl-idene and pyridinium rings is 14.73 (13)°. In the crystal, zigzag chains of alternating bromide ions and water mol-ecules associate through O-H⋯Br inter-actions run in channels approximately parallel to the b axis. These chains help form parallel chains of cations through N-H⋯O, C-H⋯N and C-H⋯Br hydrogen bonds.

(E)-1-(3,4-Dimethyl-benzyl-idene)-2,2-diphenyl-hydrazine.

Project description:The asymmetric unit of the title compound, C(21)H(20)N(2), contain two mol-ecules, both of them showing an E configuration of the C=N bond. The dihedral angles between the phenyl rings in the phenyl-hydrazone groups are 86.84?(10) and 84.85?(8)° for the two mol-ecules. Inter-molecular C-H?? inter-actions are observed in the crystal structure.

Project description:In the title compound, C23H20N3OS(+)·Br(-), the di-hydro-thia-zole ring (r.m.s. deviation = 0.015?Å) is twisted with respect to each of the C- and N-bound phenyl rings and the hy-droxy-benzene ring, making dihedral angles of 76.0?(2), 71.2?(2) and 9.8?(2)°, respectively. In the crystal, inversion-related mol-ecules are linked by association of the bromide ions with the cations via N-H?Br and O-H?Br hydrogen-bonding inter-actions. These mol-ecules run in channels parallel to the a axis through face-to-face ?-? stacking inter-actions between the hy-droxy-benzene rings [centroid-centroid distances = 3.785?(3)?Å] which, in turn, are connected into layers parallel to (110) by weak C-H?? inter-actions. A small region of electron density well removed from the main mol-ecule and appearing disordered over a center of symmetry was removed with PLATON SQUEEZE [Spek (2009 ?). Acta Cryst. D65, 148-15] following unsuccessful attempts to model it as plausible solvent molecule. The nature of the solvent was not known and hence, this is not taken into account when calculating M r and related data.

(1E,2E)-1,2-Bis(2,3-dihydro-1H-inden-1-yl-idene)hydrazine.

Project description:In the title compound, C(18)H(16)N(2), there are two independent half-mol-ecules (A and B) in the asymmetric unit, each mol-ecule being completed by an inversion center situated in the mid-point of the central N-N bond. The mol-ecules themselves therefore are essentially planar with r.m.s. deviations of 0.015 (1) and 0.020 (1) Å, respectively. In the crystal, mol-ecules are connected via C-H⋯π inter-actions in which only type B mol-ecules are donors, while both A and B mol-ecules act as acceptors. As a result, type B mol-ecules are linked into infinite chains along b, which are inter-connected by molecules of type A.
