ABSTRACT
In the title salt, C14H17N2(+)·Cl(-), the central N atom is pyramidal (sum of bond angles = 330.9°) and there is a near orthogonal relationship between the benzene rings [dihedral angle = 89.95â (10)°]. The crystal packing features N-Hâ¯Cl hydrogen bonds, which lead to a supra-molecular undulating ribbon along the a axis comprising edge-shared eight-membered {â¯HNHâ¯Cl}2 synthons. The chains are connected into layers in the ab plane by C-Hâ¯π inter-actions.
ABSTRACT
In the title hydrazonodithio-ate, C(21)H(19)N(3)OS(2), the amide group is twisted out of the plane through the S(2)C=N atoms: the C-N-N-C torsion angle is 139.71â (13)°. The pyridine ring forms dihedral angles of 52.96â (8) and 86.46â (8)° with the phenyl rings, and the latter are approximately orthogonal [dihedral angle = 76.42â (9)°]. Supra-molecular chains sustained by N-Hâ¯O hydrogen bonds and propagated by glide symmetry along the c axis are found in the crystal structure. The chains are consolidated into a three-dimensional architecture by C-Hâ¯O and C-Hâ¯N inter-actions.
ABSTRACT
In the title disulfide, C(16)H(18)S(2), the mol-ecule is twisted about the central S-S bond [the C-S-S-C torsion angle = 93.24â (7)°] and the dihedral angle between the benzene rings is 72.84â (7)°, indicating an almost orthogonal relationship; the methyl groups are orientated to the same side of the mol-ecule. The crystal packing features C-Hâ¯.π inter-actions which consolidate a three-dimensional architecture.
ABSTRACT
In the title compound, C(15)H(16)N(2)S(2), the central C(2)N(2)S(2) unit is essentially planar (r.m.s. deviation = 0.047â Å) and forms dihedral angles of 68.26â (4) and 65.99â (4)° with the phenyl and benzene rings, respectively, indicating a twisted mol-ecule. Supra-molecular chains with a step topology and propagating along [100] feature in the crystal packing, mediated through N-Hâ¯S hydrogen bonds. The chains are consolidated into a three-dimensional architecture by C-Hâ¯π inter-actions.
ABSTRACT
The title compound C(8)H(15)N(3)S has two mol-ecules in the asymmetric unit in which cis-trans isomerism is exhibited around the N(NH)C=S bonds. The cyclo-hexyl rings in both mol-ecules adopt a chair conformation. In the crystal, N-Hâ¯S hydrogen bonding produces dimers, which are inter-connected through further N-Hâ¯S hydrogen bonds, forming chains along the b-axis direction.
