Abstract

Bismuth(III) salicylate, [Bi(Hsal)₃]_n, reacts readily with the trivalent metal β-diketonate compounds M(acac) ₃ (acac = acetylacetonate; M = Al, V, Cr, Fe, Co) to produce trinuclear coordination complexes of the general formula Bi ₂(Hsal)₆·M(acac)₃ (M = Al, V, Cr, Fe, Co) in 60-90% yields. Spectroscopic and single crystal X-ray diffraction experiments indicate that these complexes possess an unusual asymmetric nested structure in both solution and solid state. Upon standing in dichloromethane solution, Bi₂(Hsal)₆·Co(acac)₃ eliminates Bi(Hsal)₃ to give the 1:1 adduct Bi(Hsal) ₃·Co(acac)₃. The 2:1 heterobimetallic molecular compounds undergo facile thermal decomposition on heating in air to 475 °C to produce heterometallic oxide materials, which upon annealing for 2 h at 700 °C form crystalline oxide materials. The synthetic approach detailed here represents a unique, general approach to the formation of heterobimetallic bismuth-based coordination complexes via the coordination of M(acac) ₃ complexes to bismuth(III) salicylate.
