The asymmetric unit of the title compound, {(C(4)H(7)N(2))[CdCl(3)(H(2)O)]}(n), contains one 1-methyl-1H-imidazol-3-ium cation, one Cd(II) atom, three Cl atoms and one water mol-ecule. Adjacent Cd ions are inter-connected alternately by paired Cl(-) bridges to generate an infinite one-dimensional coordination chain along the b axis. In the chain, the crystallographically unique Cd(II) atom, wit...

A simple approach was developed for the synthesis of methyl 4-imidazolylpyrrole-2-carboxylates from easily available compounds, 5-methoxyisoxazoles and phenacylimidazolium salts under hybrid Fe(II)/Et3N relay catalysis. The products were easily transformed into the corresponding 3-(5-methoxycarbonyl-1H-imidazol-3-ium-3-yl)pyrrol-1-ides, which in turn can be hydrolyzed under basic conditions int...

The title compound, (C(4)H(7)N(4)O)(2)[Bi(2)Cl(9)(C(4)H(7)N(4)O)]·H(2)O, was prepared by the reaction of bis-muth trichloride and 5-amino-1H-imidazole-4-carboxamide in a dilute HCl medium. The asymmetric unit contains two 5-amino-4-amino-carbonyl-1H-imidazol-3-ium cations, one edge-shared non-centrosymmetric biocta-hedral [Bi(2)C1(9)(C(4)H(7)N(4)O)](2-) dianion and a water mol-ecule. In the dia...

The synthesis of the title salt, [Ag(C(6)H(7)N(4))(2)](NO(3))(3), was carried out employing a 1:2 molar ratio of 2,2'-biimidazole and silver nitrate respectively. The cation has crystallographically-imposed C2 symmetry with the metal atom in an almost linear coordination environment [N-Ag-N = 177.01 (17)°]. The crystal structure displays N-H⋯O and C-H⋯O hydrogen-bonding inter-actions.
