Journal ArticleDOI
TL;DR: A water-soluble p-sulfonatothiacalix[6]arene (1) has been prepared in high yield and the inclusion complex with hydrated sodium cations and water has been investigated by X-ray crystal analysis.
Abstract: A water-soluble p-sulfonatothiacalix[6]arene (1) has been prepared in high yield and the inclusion complex with hydrated sodium cations and water has been investigated by X-ray crystal analysis. Host 1 formed a complex with two hydrated sodium cations with ten and sixteen water molecules.

Journal ArticleDOI
TL;DR: In this paper, the donor-stabilized silylene complex was characterized using variable-temperature NMR studies and X-ray crystal analysis, and it adopts a distorted pseudo-octahedral structure with a short W-Si bond, long Si-Cl bonds, and short contacts between the hydrides and silicon atom.

Journal ArticleDOI
TL;DR: The first anti-tricyclo[3.1.0.02,4]hexasilane was synthesized as pale yellow crystals as mentioned in this paper, which gave its skeletal isomer, tricyclo [2.2.0,0.1], in 80% yield.
Abstract: The first anti-tricyclo[3.1.0.02,4]hexasilane 1 was synthesized as pale yellow crystals. Irradiation (λ > 370 nm) of 1 gave its skeletal isomer, tricyclo[2.2.0.02,5]hexasilane 2, in 80% yield. The ...
