research communications (GM)Crystal structure and Hirshfeld surface analysis of chlorido(2,6-dimethylphenyl isocyanide)[N′-(2,6-dimethylphenyl)-N-(pyridin-2-yl)carbamimidoyl]platinum(II)
The coordination geometry around the platinum atom is square-planar. In the crystal, dimers with R22(8) motifs, formed by pairs of N—H⋯N hydrogen bonds, are connect to each other through pairs of weak C—H⋯Cl interactions, forming a R22(16) motif and creating parallel ribbons along the [011] axis direction. The molecular pairs are connected by C—H⋯π and π–π interactions, forming parallel ribbons along the b-axis direction.
research communications (GO)Molecular and crystal structure of 2,5-bis[(4-fluorophenyl)iminomethyl]furan
In the reported crystal structure, the central furan rings lies on twofold rotation axis in space group C2/c with the furan ring and imine groups of adjacent molecules participating in C—H⋯N interactions to give furan-ring-centered hydrogen-bonded chains extending along [101].
research communications (GM)Synthesis, crystal structure and Hirshfeld surface analysis of bis[2-amino-5-(ethylsulfanyl)-1,3,4-thiadiazol-3-ium] bis(perchlorato-κO)bis(picolinato-κ2N,O)copper(II)
The title copper(II) complex exhibits a distorted octahedral geometry in which the CuII cation is coordinated by the bidentate picolinate and monodentate perchlorate ligands. The crystal structure features a unique outer-sphere protonated thiadiazole cation interacting via hydrogen bonds. Hirshfeld surface analysis underscores the dominant role of O⋯H/H⋯O interactions in the crystal packing.
research communications (GO)Crystal structures and Hirshfeld surface analyses of diphenylmethyl 2-(3,5-dimethoxyphenyl)acetate and diphenylmethyl 2-(3,4,5-trimethoxyphenyl)acetate
The title compounds, C23H22O4, (I), and C24H24O5, (II), differ in the presence of a methoxy atom instead of a hydrogen atom between two methoxy groups at the phenyl ring, which greatly affects the molecular conformations and the symmetries of the crystals.
research communications (GM)Crystal structures of three 4-methylpiperidinium salts (one as three polymorphs) with tetrahalogenidoaurate(III), halide and (in one case) dichloroiodate(I) counter-anions
The structures of three 4-methylpyridinium tetrahalogenidoaurate(III) halides, one also including a dichloroiodate(I) anion, are presented. The crystal packings involve hydrogen, halogen and coinage bonds, and display prominent substructure types involving the cations and halides or the anions alone.
research communications (GM)research communications (GO)research communications (GO)Crystal structure and Hirshfeld surface analyses, crystal voids, interaction energy calculations and energy frameworks of (E)-2-[(pyren-1-ylmethylidene)amino]ethanol
The title compound contains a pyrene ring system consisting of four fused benzene rings arranged in a planar configuration. In the crystal, intermolecular O—H⋯N hydrogen bonds link the molecules into infinite chains along the c- axis direction. π–π stacking interactions between the benzene rings of adjacent molecules help to consolidate the three-dimensional architecture.
research communications (GO)Crystal structure, Hirshfeld surface, DFT and molecular docking studies of 4-bromo-2-chlorophenyl (2E)-3-[4-(pentyloxy)phenyl]prop-2-enoate
In the title compound, the aromatic rings are oriented at a dihedral angle of 83.30 (8)°. An intramolecular C—H⋯O contact generates a five-membered S(5) ring motif. In the crystal, C—H⋯O hydrogen bonds link the molecules through R12(6), R22(10), R22(14) hydrogen-bond motifs.
