ChemInform Abstract: Reaction of Oxomolybdenum Complexes with Amidoximes. Synthesis and Structure of a Nitrosylacetamidoximato(1-) Complex with a N,O-side-on Bonded Acetamidoximate(1-) Ligand: (Mo(acac)2(CH3C(NH2)NO)(NO)).

ChemInform Abstract

The title complex (III) is obtained together with a probably tetranuclear complex and separated mechanically. The formation of (III) from (I) and (II) is the first example of an amidoxime acting as a source of NO. An X-ray structure determination of (III) (space group P2₁/n, Z=4) shows that this Mo(II) 18-electron complex has a pentagonal bipyramidal geometry and is also the first example of a side-on-ligated acetamidoximate ligand.
