research communications (GO)Crystal structure and Hirshfeld surface analysis of (Z)-4-oxo-4-{phenyl[(thiophen-2-yl)methyl]amino}but-2-enoic acid
In the crystal, molecules are connected by C—H⋯O hydrogen bonds, forming C(8) chains running along the a-axis direction. Cohesion of the packing is provided by weak van der Waals interactions between the chains.
research communications (GM)Bis(2-chloro-N,N-dimethylethan-1-aminium) tetrachloridocobaltate(II) and tetrachloridozincate(II)
The competition between gauche and anti conformations in 2-chloroethyl- or 3-chloropropyldimethylammonium cations is investigated for the title tetrachlorometallate salts in which the alkyl chain is found to disordered with the gauche conformation dominant.
research communications (GO)Synthesis and crystal structures of 5,17-dibromo-26,28-dihydroxy-25,27-dipropynyloxycalix[4]arene, 5,17-dibromo-26,28-dipropyl-25,27-dipropynyloxycalix[4]arene and 25,27-bis(2-azidoethoxy)-5,17-dibromo-26,28-dihydroxycalix[4]arene
The title compounds are two calix[4]arenes with a pinched cone conformation and one with a 1,3-alternate conformation.
research communications (GI)High-resolution crystal structure of the double nitrate hydrate [La(NO3)6]2[Ni(H2O)6]3·6H2O
Very large high-quality crystals of a new member of the family of double nitrates, namely, [La(NO3)6]2[Ni(H2O)6]3·6H2O, were crystallized in large amounts. The structure was determined via single-crystal X-ray diffraction to high resolution. Extensive structural information, including hydrogen-bonding details, was obtained at the same time.
