Bismuth Aryloxides

Abstract

The synthesis and full characterization (mp, NMR, UV/vis, FTIR, and elemental analysis) of 13 bismuth aryloxides are reported. We have prepared bismuth aryloxides with alkyl, aryl, and allylic substituents on the aryl rings. Eleven of these bismuth aryloxides have been characterized with single crystal X-ray diffraction methods. Bismuth-donor interactions (donor = aryl, methoxy) are observed in several cases. Three unexpected bismuth oxo aryloxides (6c, 9c, 11c) were also isolated. Complex C(77)H(102)Bi(4)Br(6)O(8) (6c) results from apparent C-H activation and Bi-C bond formation as a sideproduct in the synthesis of Bi(O-2,6-(i)Pr(2)-4-BrC(6)H(2))(3) (6). Cluster 9c has a Bi(32)O(56) core, and cluster C(90)H(90)Bi(4)Li(2)O(12) (11c) is the second lithium bismuth oxo cluster reported to date.

Hydrolysis of a Basic Bismuth Nitrate—Formation and Stability of Novel Bismuth Oxido Clusters

“…Basically, the assembly of the layers can be described by fused [Bi 3 O 4Àx ] (2x + 1) + units as structural motifs, which have also been found in other bismuth oxido core structures. [13,19,20,26,27] As shown in Figure 2 The bismuth-oxygen coordination pattern within the high-nuclearity [Bi 38 O 45 ] 24 + core shows strong distortions assigned to the presence of the lone pair at the bismuth atom. Thus variable bismuth coordination numbers ranging from four to nine are observed.…”

A Novel Water‐Soluble Hexanuclear Bismuth Oxido Cluster – Synthesis, Structure and Complexation with Polyacrylate

“…[12,14] Additional examples of bismuth oxido clusters include the triflate [Bi 9 O 8 (OH) 6 (CF 3 SO 3 ) 5 ], [15] the phosphonate [(tBuPO 3 ) 10 12 ]. [17] The majority of these compounds have low solubility, are sensitive towards water, or are accessible only with low yield. Thus they do not hold potential for the synthesis of homogeneous hybrid materials.…”

Syntheses, Crystal Structures, and Properties of Two Quaternary Selenite/Tellurite‐Nitrates with Formula of Bi(SeO3)(NO3) and Bi3(μ3‐OH)(TeO3)3(NO3)2

“…Stacking of two trimers in the [001] direction leads to the forming of a rare hexanuclear [Bi 6 (μ 3 ‐OH) 2 (Te 3 O 10 ) 3 ] cage cluster (Figure b). All the resulting Bi–O bond distances, Bi–O–Bi, and O–Bi–O angles from this bridging type, are in the normal ranges for Bi III oxides cluster analogues . Te(1) cation lying in the mirror planes is four coordinated; its coordination geometry can be described as Ψ ‐TeO 4 tetragonal pyramid, where Ψ represents the lone pair electrons of the Te(IV) cation occupying the pyramidal site.…”
