“…Over the years, bismuth-based oxides have received considerable attention as prospective materials for a variety of applications including oxidation catalysts, high- T c superconductors, high-temperature electrolytes, nonlinear optical materials, and ferroelectrics . A field of growing importance is the synthesis of multiferroics , a class of materials that simultaneously possess two or more of the so-called “ferroic” order parameters: ferroelectricity, ferromagnetism, and/or ferroelasticity.…”

A new series of heteroleptic bismuth-transition metal β-diketonates [BiM(hfac)3(thd)2] (M = Mn (1), Co (2), and Ni (3); hfac = hexafluoroacetylacetonate, thd = tetramethylheptanedionate) with Bi:M = 1:1 ratio have been synthesized by stoichiometric reactions between homometallic reagents [Bi(III)(hfac)3] and [M(II)(thd)2]. On the basis of analysis of the metal-ligand interactions in heterometallic structures, the title compounds were formulated as ion-pair {[Bi(III)(thd)2](+)[M(II)(hfac)3](-)} complexes. The direct reaction between homometallic reagents proceeds with a full ligand exchange between main group and transition metal centers, yielding dinuclear heterometallic molecules. In heteroleptic molecules 1-3, the Lewis acidic, coordinatively unsaturated Bi(III) centers are chelated by two bulky, electron-donating thd ligands and maintain bridging interactions with three oxygen atoms of small, electron-withdrawing hfac groups that chelate the neighboring divalent transition metals. Application of the mixed-ligand approach allows one to change the connectivity pattern within the heterometallic assembly and to isolate highly volatile precursors with the proper Bi:M = 1:1 ratio. The mixed-ligand approach employed in this work opens broad opportunities for the synthesis of heterometallic (main group-transition metal) molecular precursors with specific M:M' ratio in the case when homoleptic counterparts either do not exist or afford products with an incorrect metal:metal ratio for the target materials. Heteroleptic complexes obtained in the course of this study represent prospective single-source precursors for the low-temperature preparation of multiferroic perovskite-type oxides.

“…With respect to physical characteristics that are important for advanced technology, a major target has become multimetallic bismuth(III) oxides due to their broad spectrum of potential applications including the next generation of data storage devices, high T c superconductors, solid electrolytes, nonlinear optical and luminescent materials, selective oxidation catalysts, and photocatalysts . Apart from their valuable physical properties, bismuth-containing materials have elicited considerable interest due to their potential environmentally benign alternatives to cadmium- or lead-based thermochromic systems or as “green” lubricants .…”
