research communications (GO)Crystal structures of three salts of the triphenylsulfonium ion
The crystal structures of three salts of triphenylsulfonium ion are reported, namely, triphenylsulfonium triiodide (I), triphenylsulfonium perchorate (II), triphenylsulfonium hexafluorophosphate (III).
research communications (GO)Synthesis, crystal structure and Hirshfeld surface analysis of 5,5-diphenyl-2-[2-(propan-2-ylidene)hydrazin-1-yl]-4,5-dihydro-1H-imidazol-4-one N,N-dimethylformamide hemisolvate
The asymmetric unit consists of two independent molecules of the substituted imidazolone having different conformations, and one molecule of solvent DMF. The two imidazolone molecules are linked by N—H⋯N and C—H⋯O hydrogen bonds and the DMF is joined to one of these by a N—H⋯O hydrogen bond. Additional N—H⋯N and C—H⋯O hydrogen bonds link these groups into corrugated layers parallel to the (101) plane with the layers joined by C—H⋯π (ring) interactions.
research communications (GM)Crystal structure of poly[μ3-acetato-diaqua-μ3-sulfato-cerium(III)]: serendipidous synthesis of a layered coordination polymer exhibiting interlayer O—H⋯O hydrogen bonding
In the crystal structure of the title compound, the CeIII cations are ninefold coordinated and linked into chains via the acetate anions and are further connected into layers by the sulfate dianions.
research communications (GM)(2,9-Dimethyl-1,10-phenanthroline)bis[2-(pyridin-2-yl)phenyl]iridium(III) hexafluorophosphate and (2,9-dimethyl-1,10-phenanthroline)bis[5-methyl-2-(pyridin-2-yl)phenyl]iridium(III) hexafluorophosphate–diethyl ether–acetonitrile (1/0.61/0.78)
The title compounds exhibit Ir—C and Ir—N bond lengths typical of cyclometallated iridium compounds with phenylpyridine ligands. Methylation of the phenanthroline ligand leads to longer Ir—N bond lengths compared to the unmethylated analog.
