Reductive nitrosylation of tetraoxometallates. Part VIII 1. A virtually single step synthesis of azido-nitrosyl derivatives of chromium(I) directly from chromate in aqueous-aerobic media.

Abstract

Azido-nitrosyl complexes and their derivatives of the types [Cr(NO)(N 3) 5] 3− and [Cr(NO)(N 3) 2(L-L)] [L-L = 2,2′bipyridine (bipy) and 1,10 phenanthroline (phen)] were synthesised directly from chromate ion using hydroxylamine hydrochloride, azide ion and hydroxyl ion and other appropriate ligands virtually in a single step process in an aqueous aerobic medium. The compounds are characterised by IR, molecular weight, molar conductance, magnetic susceptibility, esr and electronic spectral data.
