The title compound, C13H20Cl3N2O4P, was prepared by the reaction of N-isopropylbenzylamine and CCl3C(O)N(H)P(O)Cl2, followed by crystallization from CH3OH and CH3CN. Centrosymmetric dimers of anions are hydrogen-bonded to neighbouring cations (via –P—O...H—N– and –C=O...H—N– hydrogen bonds) in a one-dimensional polymeric chain. Furthermore, a Cl...Cl interaction (3.242 Å) and a C—H...π short contact are present in the crystal structure, the former between two adjacent anions and the latter between two neighbouring cations.

Centrosymmetric Dimers

In the molecule of the title compound, C14H10Cl2N2OS, the dihedral angle between the two aromatic rings is 38.58 (6)°. In the crystal structure, centrosymmetric dimers are formed via intermolecular N—H...S hydrogen bonds [N...S = 3.4798 (16) Å]. These dimeric units are, in turn, connected by weak intermolecular C—H...O hydrogen bonds, forming one-dimensional chains along [100].

Hydrogen Bonded

The crystal structure of the title compound {(C5H14N2)2[Cd2Cl8]} n , (I), consists of hydrogen-bonded 2-methylpiperazinediium (H2MPPA2+) cations in the presence of one-dimensional polymeric {[CdCl3(μ3-Cl)]2−} n anions. The CdII centres are hexacoordinated by three terminal chlorides and three bridging chlorides and have a slightly distorted octahedral CdCl3(μ3-Cl)3 arrangement. The alternating CdCl6 octahedra form four-membered Cd2Cl2 rings by the sharing of neighbouring Cd–Cl edges to give rise to extended one-dimensional ladder-like chains parallel to the b axis, with a Cd...Cd distance of 4.094 (2) Å and a Cd...Cd...Cd angle of 91.264 (8)°. The H2MPPA2+ cations crosslink the [CdCl3(μ3-Cl)] n chains by the formation of two N—H...Cl hydrogen bonds to each chain, giving rise to one-dimensional ladder-like H2MPPA2+–Cl2 hydrogen-bonded chains [graph set R 4 2(14)]. The [CdCl3(μ3-Cl)] n chains are interwoven with the H2MPPA2+–Cl2 hydrogen-bonded chains, giving rise to a three-dimensional supramolecular network.

The title compound, C22H22O3, demonstrates a two-photon absorption. Its metrical parameters are similar to those of related cyclohexanone derivatives. In the crystal structure, two sets of centrosymmetric dimers formed by weak C—H...O intermolecular hydrogen bonds combine to form molecular tapes along [101].

The title compound, C6H11NO3S, provides entries to novel carbamoyl disulfanes and related compounds of interest to our laboratory. The atoms of the central O(C=S)N(C=O)O fragment have an r.m.s. deviation of 0.1077 Å from the respective least-squares plane. While several conformational orientations are conceivable, the crystal structure shows only the one in which the carbonyl and the thiocarbonyl moieties areantito each other across the central conjugated C—N—C moiety. Pairs of 2.54 Å N—H...S=C hydrogen bonds between adjacent molecules form centrosymmetric dimers in the crystal.

In the title compound, C29H25FN2O4, the mean planes of the two indole ring systems (r.m.s. deviations = 0.1392 and 0.0115 Å) are approximately perpendicular to one another, subtending a dihedral angle of 86.0 (5)°; the benzene ring is twisted with respect to the mean planes of the two indole ring systems by 83.3 (2) and 88.1 (4)°, respectively. In the crystal, pairs of N—H...O hydrogen bonds link the molecules into centrosymmetric dimers, which are further linked by N—H...O hydrogen bonds into supramolecular chains propagating along the [101] direction.

Ring Motif

Mutual carboxyl–carboxyl O—H...O hydrogen bonds link the molecules of the title compound, C7H5BrO3, into centrosymmetric dimers which display a centralR22(8) ring motif. In addition, there is an intramolecular hydroxyl–carboxyl O—H...O interaction present. A comparison with the crystal structures of 59 other substituted derivatives of salicylic acid shows that both the centrosymmetric carboxyl–carboxyl O—H...O dimer and the stacking mode of molecules along the shortaaxis observed in the title structure are frequent packing motifs in this set.
