The complex crystallizes with two molecules in the asymmetric unit. The rhodium center has a distorted square-planar conformation, formed by a cycloocta-1,5-diene (COD) ligand, an N-heterocyclic carbene (NHC) ligand, and a chloride ligand.
A new neutral triazole-based N-heterocyclic carbene rhodium(I) complex [RhCl(C8H12)(C8H15N3)], has been synthesized and structurally characterized. The complex crystallizes with two molecules in the asymmetric unit. The central rhodium(I) atom has a distorted square-planar coordination environment, formed by a cycloocta-1,5-diene (COD) ligand, an N-heterocyclic carbene (NHC) ligand, and a chlorido ligand. The bond lengths are unexceptional. A weak intermolecular non-standard hydrogen-bonding interaction exists between the chlorido and NHC ligands.
The title compound is a binuclear complex of molybdenum with a ethylenediaminetretraacetate ligand bridging two MoO3 units.
The title compound, (C2H10N2)2[(C10H12N2O8)(MoO3)2]·4H2O, which crystallizes in the monoclinic C2/c space group, was obtained by mixing molybdenum oxide, ethylenediamine and ethylenediaminetetraacetic acid (H4edta) in a 2:4:1 ratio. The complex anion contains two MoO3 units bridged by an edta4− anion. The midpoint of the central C—C bond of the edta4− anion is located on a crystallographic inversion centre. The independent Mo atom is tridentately coordinated by a nitrogen atom and two carboxylate groups of the edta4− ligand, together with the three oxo ligands, producing a distorted octahedral coordination environment. In the three-dimensional supramolecular crystal structure, the dinuclear anions, the organoammonium counter-ions and the solvent water molecules are linked by N—H⋯Ow, N—H⋯Oedta and O—H⋯O hydrogen bonds.

The crystal structure of the organic salt features classical hydrogen-bonding interactions involving the 8-hydroxyquinolinium cation, the naphthalene-1,5-disulfonate anion and the two water molecules of crystallization.
The interaction between 8-hydroxyquinoline (8HQ, C9H7NO) and naphthalene-1,5-disulfonic acid (H2NDS, C10H8O6S2) in aqueous media results in the formation of the salt hydrate bis(8-hydroxyquinolinium) naphthalene-1,5-disulfonate tetrahydrate, 2C9H8NO+·C10H6O6S22−·4H2O. The asymmetric unit comprises one protonated 8HQ+ cation, half of an NDS2– dianion symmetrically disposed around a center of inversion, and two water molecules. Within the crystal structure, these components are organized into chains along the [010] and [10
In the title compound, the central MnII ion is coordinated by four pyrrole N atoms of the porphyrin core in the basal sites and one N atom of the 2,5-dimethylimidazole ligand in the apical site. Two chlorobenzene solvent molecules are also present in the asymmetric unit.
In the title compound, [Mn(C68H44N12O4)(C5H8N2)]·2C6H5Cl, the central MnII ion is coordinated by four pyrrole N atoms of the porphyrin core in the basal sites and one N atom of the 2,5-dimethylimidazole ligand in the apical site. Two chlorobenzene solvent molecules are also present in the asymmetric unit. Due to the apical imidazole ligand, the Mn atom is displaced out of the 24-atom porphyrin mean plane by 0.66 Å. The average Mn—Np (p = porphyrin) bond length is 2.143 (8) Å, and the axial Mn—NIm (Im = 2,5-dimethylimidazole) bond length is 2.171 (8) Å.
