The asymmetric unit of the title compound, [Cd(C(30)H(31)N(3)O(6))(2)](PF(6))(2)·3H(2)O, contains one half-cation with the Cd(II) center situated on a twofold rotational axis, one hexa-fluoridophosphate anion and two uncoordinated water mol-ecules, one of which is also situated on a twofold rotational axis. The cations are associated into columns along the(More)
The crystal structures of the monoclinic and triclinic polymorphs of zoledronic acid, C5H10N2O7P2, have been established from laboratory powder X-ray diffraction data. The molecules in both polymorphs are described as zwitterions, namely 1-(2-hydroxy-2-phosphonato-2-phosphonoethyl)-1H-imidazol-3-ium. Strong intermolecular hydrogen bonds (with donor-acceptor(More)
Eleven complexes of a hybrid ligand 4'-(4'''-benzo-15-crown-5)-methyloxy-2,2':6',2''-terpyridine (L) were synthesized and characterised by elemental analysis, IR-spectroscopy and X-ray analysis. The crystal structures of seven complexes were determined either from single-crystal data ([NaNCS.L] (6)and [CuL2.NaNCS.Na(NCS)2]+.NCS-.CH3CN) (11) or from powder(More)
Afobazole {systematic name: 2-[2-(morpholin-4-yl)ethylsulfanyl]-1H-benzimidazole} is a new anxiolytic drug and Actins, Auzins & Petkune [(2012). Eur. Patent EP10163962] described four polymorphic modifications. In the present study, the crystal structures of two monoclinic polymorphs, 5-ethoxy-2-[2-(morpholin-4-ium-4-yl)ethylsulfanyl]-1H-benzimidazol-3-ium(More)
