Abstract Crystallization of [(Ph3Sn)2SeO4] ⋅ 1.5H2O in methanol leads to the formation of [{(Ph3Sn)2SeO4} ⋅ CH3OH] n (1) which constitutes a new specimen of organotin(IV) selenate derivatives. In the solid state, complex 1 is arranged in polymeric zig-zag chains, composed of alternating Ph3Sn and SeO4 groups. In addition, pendant Ph3Sn ⋅ CH3OH moieties are branched along chains according to a syndiotactic organization and via Sn-O-Se connections. From a supramolecular point of view, intermolecular hydrogen bonds established between the selenate groups (uncoordinated oxygen) and the hydroxyl functions (CH3OH) of the pendant groups link the chains together.

Centrosymmetric Dimers

The solid-state structures of a l-(φ-ammoniopropyl)-2-(2-thienylcarbonyl)-cyclopentadienide (2) and a l-(φ-ammoniopentyl)-2-(4-methoxybenzoyl)-cyclopentadienide (3) have been determined. Both betaines self-assemble by NH ··· O hydrogen bonds, but the motifs are different. In the ammoniopropyl case, both intramolecular and intermolecular hydrogen bonds of this type exist, the latter bond being responsible for the formation of infinite chains. In the ammoniopentyl case, intermolecular hydrogen bonds build up a two-dimensional network which contains centrosymmetric dimers held together by NH ··· O=C-aryl hydrogen bonds.

Crystal structures have been determined for inclusion complexes of the host molecule 9,10-dihydro-9,10-ethenoanthracene-11,12-bis(diphenylmethanol), with acetone, ethanol and toluene as guest solvent molecules. The host molecule exhibits an intramolecular O--H...O hydrogen bond in each of the complexes, with intermolecular hydrogen bonds to the acetone and ethanol guests. Different photoproducts are obtained from solution and solid-state photolyses; the solid-state reaction involves a relatively small amount of molecular rearrangement, for which a mechanism is proposed.

Π Stacking

Compounds containing benzimidazole moiety in solid state often demonstrate the ability to the formation of π-π stacking interactions. In this work, we focused on the investigation of intermolecular hydrogen bonds and parallel displaced (PD) π-π stacking interactions found in the crystals of titled molecules, both crystallize with Z = 2 in the space group P-1. Differences of the π-π stacking interactions parameters depending on the volume of side aromatic substituent in a homologous series, as well as a theoretical estimation of the energy of these interactions using DFT at two different functionals (M06-2X, MPWB95) and three basis sets [6-31G(d), 6-31++G, and 6-31++G(d)] were shown.

A salt with the composition [C12H9N2][C8H3Cl2O4] (1) with 4,5-dichlorophthalic acid and 1,10- phenanthroline (phen) has been synthesized and characterized by IR, UV spectroscopy, elemental analysis, and X-ray crystallography. Compound 1 represents a 3D chiral supramolecular framework containing monohelical chains (21 axis) through multiform C-H· · ·O, O-H· · · O, N-H· · ·N intramolecular hydrogen bonds and C-H· · ·O, N-H· · ·O intermolecular hydrogen bonds. Otherwise, two types of face-to-face π · · ·π interactions between the aromatic rings are found in the solid state. The luminescent properties of compound 1 were investigated in the solid state at room temperature

Guanidinium Salts

1,2,3-Triaminoguanidinium chloride was combined with benzaldehyde and hydratropic aldehyde to furnish the corresponding tris(imines), which were converted into 1,2,3-tris(benzylamino)guanidinium salts by catalytic hydrogenation in the former, and by borane reduction in the latter case. The resulting alkyl-substituted triaminoguanidinium salts underwent a threefold carbamoylation with aryl isocyanates to furnish 1,2,3-tris(ureido)guanidinium salts, while p-toluenesulfonyl isocyanate led only to a mono-ureido guanidinium salt. With aryl isothiocyanates, 3-hydrazino-1H-1,2,4-triazole-5(4H)-thione derivatives were obtained. Compounds 7a and 8 show interesting solid-state structures with intra- and intermolecular hydrogen bonds.

Force Method

A study of the infrared and Raman spectra of previously synthesized phthalimide-15N-H and phthalimide-15N-D has been carried out. With the new data obtained, the vibrational spectra of the phthalimide molecule in a C2 v* symmetry has been reassigned, but taking into account that the molecule in the solid state forms dimers bonded by intermolecular hydrogen bonds; these dimers have a Ci symmetry. On the other hand, a semi-empiric calculation of the force fields of this molecule has been carried out by the MINDO/3-FORCE method, which required a prior optimization of the molecular geometry; the force field was transformed to the space of internal coordinates.
