Crystal structures of methyl 3,5-di­methyl­benzoate, 3,5-bis­(bromo­meth­yl)phenyl acetate and 5-hy­droxy­benzene-1,3-dicarbaldehyde

The crystals of methyl 3,5-di­methyl­benzoate are composed of strands of C—H⋯O=C bonded mol­ecules, which are further arranged into layers. As a result of the presence of two bromo­methyl substituents in 3,5-bis­(bromo­meth­yl)phenyl acetate, mol­ecular dimers formed by crystallographically non-equivalent mol­ecules are connected to structurally different two-dimensional aggregates in which the bromine atoms participate in Br⋯Br bonds of type I and type II. In the case of 5-hy­droxy­benzene-1,3-dicarbaldehyde,which possesses three donor/acceptor substituents, the mol­ecular association in the crystal creates a close three-dimensional network comprising C_ar­yl—H⋯O_hy­droxy, C_form­yl—H⋯O_form­yl and O—H⋯O_form­yl bonds.

Crystal structure and Hirshfeld surface analysis of 2-chloro-N-(4-meth­oxy­phen­yl)acetamide

The meth­oxy group lies very close to the plane of the phenyl ring while the acetamido group is twisted out of this plane. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds form layers of mol­ecules parallel to the ab plane. The layers are connected by C—H⋯Cl hydrogen bonds and C—H⋯π(ring) inter­actions, forming a three-dimensional structure.

Crystal structure and Hirshfeld surface analysis of 2,2′-(phenyl­aza­nedi­yl)bis­(1-phenyl­ethan-1-one)

The whole mol­ecule of the title compound is generated by twofold rotational symmetry. In the crystal, mol­ecules are linked by inter­molecular C—H⋯O inter­actions with (12) ring motifs, and C—H⋯π inter­actions, resulting in ribbons along the c-axis direction. The mol­ecular packing is consolidated by van der Waals inter­actions between these ribbons.

In the crystal, neighboring mol­ecules are linked into layers parallel to the (200) plane via C—H⋯O hydrogen bonds and C—H⋯π inter­actions. van der Waals inter­actions between parallel mol­ecular layers help to strengthen the packing.

Crystal-structure studies of 4-phenyl­piperazin-1-ium 4-eth­oxy­benzoate monohydrate, 4-phenyl­piperazin-1-ium 4-meth­oxy­benzoate monohydrate, 4-phenyl­piperazin-1-ium 4-methyl­benzoate monohydrate and 4-phenyl­piperazin-1-ium tri­fluoro­acetate 0.12-hydrate

Four novel piperazinium salts are reported, and based on 1-phenyl­piperazinium as a common cation in the asymmetric units that include additionally water mol­ecules, and different P-substituent benzoate anions or a tri­fluoro­acetate anion. They are hydrated and there are three crystallized as 1:1 salts while the fourth is a 2:2 salt. Their crystal packing depends on strong ribbons or sheets stabilized by hydrogen bonds of type N—H⋯O and O—H⋯O and other inter­actions as C—H⋯O, C—H⋯π and C—H⋯F in the tri­fluoro­acetate-based one.

C—H⋯Br inter­actions connect mol­ecules in the crystal, resulting in zigzag C(8) chains along the [100] direction. C—Br⋯π inter­actions connect these chains into parallel layers to (002). van der Waals inter­actions between the layers aid in the cohesion of the crystal packing.

Synthesis and crystal structure of 2-(2-hy­droxy­phen­yl)-1,3-bis­(4-meth­oxy­benz­yl)-1,3-diazinan-5-ol

The title compound resulted from the condensation reaction between 1,3-bis­{[(4-meth­oxy­phen­yl)meth­yl]amino}­propan-2-ol and 2-hy­droxy­benzaldehyde in CH₃OH. The structure exhibits disorder of one of the 4-meth­oxy­benzyl groups, the hy­droxy group bonded to the 1,3-diazinan ring, and the methyl group of the meth­oxy residue. The crystal packing is sustained by C—H⋯O and O—H⋯π inter­actions, giving rise to infinite chains running along the b-axis direction.
