research communications (GM)Syntheses and structures of two coordination polymers formed by Ni(cyclam)2+ cations and sulfate anions
The coordination polyhedra of the complex cations in the one-dimensional title coordination polymers represent tetragonally distorted trans-NiN4O2 octahedra with the four N atoms of the macrocyclic ligand forming the equatorial plane and two O atoms of the sulfate anions occupying the axial positions.
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)Crystal structure of di-μ-acetato-κ4O:O′-bis{(acetato-κ2O,O′)tetraaqua[1-(pyridin-2-ylmethylidene-κN)-2-(pyridin-2-yl-κN)hydrazine-κN1]lanthanum(III)} dinitrate hemihydrate
In the title Schiff base binuclear lanthanum(III) complex, the two metal ions have the same environment and the LaIII ion is coordinated by three soft nitrogen atoms from the Schiff base ligand, four hard oxygen atoms from carboxylate co-ligands and two water oxygen atoms. Each LaIII ion is nine coordinate and its environment is best described as a tricapped trigonal–prismatic geometry.
research communications (GO)A new hydrated crystalline form of N-[(E)-(4-hydroxyphenyl)methylidene]-1H-1,2,4-triazol-3-amine and its antifungal activity
The synthesis, crystal structure, Hirshfeld surface analysis, and antifungal assessment of a new monohydrated Schiff base with a triazole moiety are reported.
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.
