Nature of the ‘[Ir(bpy)2(H2O)(bpy)]3+’, (bipy = 2,2′-bipyridine) cation. Monodentate or covalently hydrated bipyridine ligand? X-Ray crystal structure of the perchlorate salt

A single-crystal X-ray structural study of the ClO4– salt of the title cation demonstrates this species contains neither a monodentate nor a covalently hydrated bipyridine ligand; all three bipyridine ligands are chelated to iridium(III) but one bipyridine ligand is ligated via the nitrogen of one ring and the C(3) carbon of the other ring, reminiscent of orthometallated compounds.

Interligand pockets in polypyridyl complexes. The crystal and molecular structure of the Cr(2,2′,2″-terpyridine)23+ ion

A single crystal X-ray study reveals that the title compound possesses a distorted meridional configuration; the interligand pockets are such that, in aqueous solutions, the CrIII core may be considered solvated by water molecules.

Preparation of Symmetrical and Unsymmetrical Diorganotellurium Dichlorides Using Organolead Compounds

Abstract The synthesis of symmetrical and unsymmetrical diorganotellurium dichlorides in good yields via the cleavage reactions of lead-lead and lead-carbon bonds by tellurium tetrachloride and monoaryltellurium trichlorides is reported.

Conformational preferences in some aryl substituted heterocyclic compounds exhibiting restricted internal rotation about C–N bonds

X-Ray studies of the thermodynamically less stable (in solution) diastereoisomeric rotational isomer of 3-(2-bromophenyl)-5-methyl-2-thiohydantion (II) show that the bromine atom is transoid to the 5-methyl group.

Novel dimer of pentane-2,4-dione. The crystal and molecular structure of the cation (C10H13O2)+

Reaction of a pentane-2,4-dionate salt with dimethyldichlorosilane yields a bright yellow compound; X-ray structure analysis reveals it to be the novel substituted pyrylium species, 6-(2-hydroxy-prop-1-enyl)-2,4-dimethylpyrylium chloride (III).

Heterobimetallic synthesis using the tripod ligand, HC(PPh2)3: the X-ray structure of [(CO)5FeRh(tripod)]+

The tripod ligand, HC(PPh2)3, can be used to construct heterobimetallic complexes such as [(CO)5FeRh(tripod)]+, the X-ray structure of which shows the presence of a metal–metal bond.

An unusual bonding mode for a dithiocarboxylate ligand: a tetradentate interaction; X-ray crystal structure of the product of the reaction of nonacarbonyldi-iron with 1,2-benzodithiole-3-thione

The compound 1,2-benzodithiole-3-thione (1), on reaction with Fe2(CO)9, incorporates two Fe2(CO)6 units giving complex (2), the structure of which has been determined by X-ray crystallography; it contains a novel tetradentate RCS2 ligand possessing an iron–carbon bond.
