Solvolytic routes to new nonabismuth hydroxy- and alkoxy-oxo complexes: synthesis, characterization and solid-state structures of novel nonabismuth polyoxo cations Bi9(µ3-O)8(µ3-OR)65+(R = H, Et)

Abstract

Base hydrolysis of BiO(ClO4) yields ClO4- salts of the novel nonabismuth polyoxo cation Bi9(mu3-O)8(mu3-OH)6(5+); ethanolysis converts to the ethoxide Bi9(mu3-O)8(mu3-OEt)6(5+).

Polynuclear Bismuth‐Oxo Clusters: Insight into the Formation Process of a Metal Oxide

“…[51] It was only very recently that the first nonanuclear bismuth-oxo-hydroxo cation was isolated, namely [Bi 9 -(m 3 -O) 8 (m 3 -OH) 6 ] 5 + . [52] The basic building unit is described as a [Bi 4 (m 3 -O) 2 (m 3 -OH) 4 ] subunit, which is similar to the basic structural motif of [Bi 4 (m 3 -O) 2 (OSiEt 3 ) 8 ] (5). Interestingly, a hexanuclear {Bi 6 } motif of type A is not observed.…”

Cost efficient synthesis of bismuth aminoalkoxides from bismuth oxide: Molecular structure of [Bi2(mdea)2(mdeaH)2](mdeaH2)2

“…Unfortunately, no suitable crystals could be grown for 3 or the oxo clusters 4 or 5 but the presence of bismutyl species for the later is likely [22].…”

Towards a Structural Understanding of the Anti‐Ulcer and Anti‐Gastritis Drug Bismuth Subsalicylate

“…[26] While inorganic ternary bismuth oxide clusters of high nuclearity are not unexpected, [27][28][29] similar metal-organic compounds of bismuth, including those with ethoxide, trifluoroacetate, phosphonate, and citrate ligands are now apparent. [30][31][32][33][34] In addition, Whitmire and co-workers have recently incorporated bismuth and salicylate anions and dianions into several structurally characterized heterobimetallic clusters containing Al or a series of transition metals, [35][36][37][38] generally of low nuclearity. Mehring and co-workers have proposed a set of rules to describe the growth pattern of bismuth oxo clusters, including homometallic oxo clusters containing 4, 9, 18, 20, and 22 bismuth atoms, in addition to several larger heterobimetallic clusters incorporating sodium which were derived from partial hydrolysis of bismuth silanolates.…”
