Structural Diversity and Thermochromic Properties of Iodobismuthate Materials Containing d-Metal Coordination Cations: Observation of a High Symmetry [Bi3I11]2− Anion and of Isolated I− Anions

“…The [Bi 2 I 9 ] 3− anion of the structure, which consists of two BiI 6 octahedra sharing one face, also sits on a site of D 3 crystallographic symmetry, while the I − anion sits on a site of S 6 symmetry. The [Bi 2 I 9 ] 3− anion has been frequently observed in iodobismuthate chemistry, ,,,,,, and this species is the only commonly occurring iodobismuthate anion exhibiting face-sharing of BiI 6 octahedra. However, isolated I − anions are not commonly observed in iodobismuthate chemistry, with the only known examples of this occurring in [C 6 H 5 (CH 2 ) 2 NH 3 ] 4 [BiI 6 ][I]·H 2 O and [CH 3 (CH 2 ) 3 NH 3 ] 6 [BiI 6 ][I] 2 [I 3 ] prior to this report of [Co(TMPhen) 3 ] 2 [Bi 2 I 9 ][I].…”

Exciton-phonon interactions in the Cs3Bi2I9crystal structure revealed by Raman spectroscopic studies

“…Bismuth halide semiconductors have been extensively investigated in recent years due to their excellent optical and electrical properties and interesting layered crystal chemistry based on octahedra of [BiI 6 ], with the self‐assembly ability for creating particular molecular structures of [Bi x I y ] . Similarly to the case of the layered semiconductor structure of PbI 2 , the octahedral packages of BiI 6 create a rich aggregation diversity of multinuclear clusters of different chemical efficiencies, such as [Bi 2 I 9 ] 3− , with one‐share crystalline faces , and [Bi 3 I 11 ] 2− or [Bi 4 I 16 ] 4− , with two‐ or three‐share faces.…”

“…However, it is important to note that by the increase of the molecular cluster structure, a reduction of the highest occupied molecular orbital (HOMO)–lowest unoccupied molecular orbital (LUMO) gap is expected, accompanied by the extension of the orbital molecular levels that create valence and conduction bands , which creates a wide range of materials with extensive optical and electrical study opportunities. In this context, several studies that have been performed in the past on hybrid organic‐inorganic bismuth halides , have attracted attention especially currently . Remarkable progress in this area regarding the different possibilities for the intercalation of various organic compounds, with great potential for applications in the field of solar cells , has been revealed due to the suitable bandgaps for the increasing light absorption efficiency.…”

Layered Heterometallic Iodoplumbate Containing a Novel Pb3Cu6I16 Net: Structure and Optical Properties

“…Compounds containing metals other than Pb, for example, Sn, Bi, Sb, Ag, and Cu, are known and have been synthesized using a variety of organic counterions, as well as, more recently, transition-metal coordination compounds. − Among those, the iodocuprates have been extensively investigated, and the work, in particular, of Hartl and co-workers has resulted in the synthesis and characterization of a large number of copper iodide clusters, including Cu 5 I 7 2- , Cu 6 I 10 4- , Cu 6 I 11 5- , Cu 8 I 13 5- , and Cu 36 I 56 20- , while other systems have given rise to extended Cu 3 I 4 - and CuI 2 - chains. − …”
