Dibromidooxido[(Z)-N′-(propan-2-ylidene)benzohydrazidato](triphenylphosphane)rhenium(V)

Abstract

The asymmetric unit of the title neutral rhenium(V) coordination compound, [ReBr2(C10H11N2O)O(C18H15P)], contains two mol­ecules. In each of the two molecules the metal atom is octa­hedrally coordinated, the bromido ligands being cis-orientated. The chelate ligand is present in its imine-tautomeric form. In the crystal, C—H⋯Br contacts connect the mol­ecules into chains along [101]. The shortest inter­centroid distance between two aromatic rings was found to be 3.906 (2) Å.

“…Imines are easily obtained upon condensation reaction of primary amines with carbonyles (aldehydes and ketones alike). They have found application as ligands in transition metal chemistry, and their role as potential chelating agents has been confirmed on grounds of diffraction studies based on single crystals [7][8][9][10][11]. In continuation of our interest in the structural aspects of diverse imine compounds [12][13][14][15][16][17][18] the title compound was synthesized and investigated by means of a diffraction study based on single crystals.…”
