Coordination chemistry of homoatomic ligands of bismuth, selenium and tellurium

Weak Interactions under Pressure: hp‐CuBi and Its Analogues

“…Forthe investigated 3d transition-metal compounds of bismuth, the required readjustment of the chemical equilibrium is realized by adapting the pressure.I n contrast, the more electronegative 4d and 5d elements rhodium and iridium reveal markedly greater charge transfer and form binary bismuth compounds without supporting compression: To characterize the atomic interactions directly in position space,t he electron localizability indicator (ELI-D) was employed as aq uantum-chemical tool. [28,29] This was first discovered in RhBi 4 as the spatial separation of two interpenetrating 3D frameworks built by edge-condensed RhBi 8 antiprisms. Foratoms in distinct coordination environments,t he outermost (valence) shell region displays strong deviations from the spherical distribution, yielding local attractors that are fingerprints for different chemical bonding scenarios.…”

Characteristics, Applications and Determination of Bismuth

“…Bi (III) shows strong attractive force to both oxygen and nitrogen ligands. [33][34][35][36][37][38][39] However, when exposed to thiol-containing ligands, such as cysteine and glutathione, Bi (III) prefers to form complexes via thiolate bonding (-SR). It has been reported that the coordination number (CN) of bismuth complexes with aminopolycarboxylate and polyaminopolycarboxylate ligands ranges from 3 to 10, indicating that the structures of these compounds are irregular, such as pyramid-shaped (CN: 3) and tricapped trigonal prism (CN: 9), [Bi(OH 2 9 ](CF 3 SO 3 3 .…”
