Abstract
The title compound, C16H13N3OS, comprises an oxa-diazo-lethione ring bound to the N atom of an almost planar carbazole ring system (r.m.s. deviation = 0.0088 Å) through an ethyl-ene chain. The oxa-diazole ring is inclined to the the carbazole ring system by 40.71 (6)°. In the crystal, N-H⋯O, N-H⋯S, C-H⋯N and C-H⋯S hydrogen bonds combine with C-H⋯π(ring) and π-π contacts to stack the mol-ecules along the b-axis direction.

Abstract
The closely related title compounds, 3-(2,5-dimeth-oxy-3,4,6-tri-methyl-phen-yl)propyl methacrylate, C18H26O4 (I), and 3-(2,4,5-trimethyl-3,6-dioxo-cyclo-hexa-1,4-dien-yl)propyl methacrylate, C16H20O4 (II), are monomers suitable for the preparation of redox polymers. They consist of a propyl-methacrylate group and three methyl substituents on di-meth-oxy-benzene and quinone cores, respectively. Both crystal structures feature weak C-H⋯O hydrogen bonds and C-H⋯π(ring) contacts between methyl groups and the six-membered rings.

Abstract
In the title compound, C15H22O4, the fully substituted benzene ring carries a methyl propanoate, two methoxy and three methyl substituents. Both methoxy substituents are almost orthogonal to the benzene ring plane. The methyl propanoate group is almost planar, r.m.s. deviation 0.0138 Å, and is inclined to the benzene ring plane by 80.26 (14)°. In the crystal, C—H...O hydrogen bonds form head-to-tail chains of molecules along theb-axis direction that are supported by very weak C—H...π(ring) contacts.

Abstract
The title compound, C24H21ClN2O, crystallizes with two unique mol-ecules in the asymmetric unit. In each mol-ecule, the central imidazole ring is substituted at the 2-, 4- and 5-positions by benzene rings. The 2-substituted ring carries a Cl atom at the 4-position. One of the imidazole N atoms in each mol-ecule has a propan-2-ol substituent. In the crystal, a series of O-H⋯N, C-H⋯O and C-H⋯Cl hydrogen bonds, augmented by several C-H⋯π(ring) inter-actions, generate a three-dimensional network of mol-ecules stacked along the a-axis direction.

Abstract
Abstract
Morpholinium hydrogen sulfate as an ionic liquid was employed as a catalyst for the synthesis of a biologically active series of multi-substituted imidazoles by a four-component reaction involving the combination of benzil with different aromatic aldehydes, ammonium acetate, and 1-amino-2-propanol under solvent-free conditions. The key advantages of this method are shorter reaction times, very high yield, and ease of processing. Furthermore, the resulting products can be purified by a non-chromatographic method and the ionic liquid catalyst is reusable. All of these novel compounds have been fully characterized from spectral data. The X-ray crystal structures of two representative molecules are also detailed.

Abstract
The title molecule, [Fe2(C5H5)2(C12H8O3)], briefly reported previously [Zhang (2015). Private Communication (CCDC reference 1056736). CCDC, Cambridge, England], comprises two ferrocenyl units connected by an acid anhydride bridge. Both ferrocene units have near coplanar [dihedral angles between the ring planes = 2.84 (4) and 1.74 (13)°] and eclipsed [pseudo torsion angles = 6.3 (2) and 5.1 (2)°] cyclopentadienyl (Cp) rings. A twist through the anhydride linkage results in a dihedral angle of 73.81 (8)° between the two substituted Cp rings planes. An intramolecular C—H...O hydrogen bond is also found. In the crystal, C—H...O hydrogen bonds link the molecules into a three-dimensional network.
