[N′-(5-Chloro-2-oxidobenzyl-κO)-2,4-dihydroxybenzohydrazidato-κ2N′,O](methanol-κO)dioxidomolybdenum(VI)–4,4′-bipyridine (1/1)

Abstract

In the title co-crystal, [Mo(C14H9ClN2O4)O2(CH3OH)]·C10H8N2, the deprotonated Schiff base O,N,O′-chelates to the MoVI atom, the three atoms involved in chelation comprising the fac sites of the octahedron surrounding the methanol-coordinated metal atom. The methanol molecule forms an O—H...N hydrogen bond to an N atom of the 4,4′-bipyridine solvent molecule; the hydroxy group of the Schiff base forms an O—H...N hydrogen bond to the other N atom of another molecule. The two hydrogen bonds leading to the formation of a helical chain running along the b axis.
