Thiothixeneβ2HCl forms three different hydrates on exposure to water vapour. These have been characterised by X-ray powder diffraction. The dehydration reaction of the monohydrate follows the first-order rate law with Ea = 125(22) kJ mol-1. The dehy

Platinum(II) and palladium(II) complexes of N-benzoyl-N ′-propylthiourea (H2L): synthesis and geometric isomer distribution of [M(H2L-S )2X2] (M = PtII or PdII; X = Cl−, Br− or I−); crystal structure of trans-[Pd(H2L-S )2Br2]

A systematic study of the synthesis and cis/trans isomer distribution for simple [M(H2L-S)2X2] complexes (M = PtII or PdII; X = Cl, Br or I; H2L = N-benzoyl-N′-propylthiourea) has shown that the pure cis-[Pt(H2L-S)2Cl2] complex is obtained prior to

Crystal Structure and Desolvation Kinetics of a Methanol Inclusion Compound of trans-9,10-dihydroxy-9,10-di-p-tert-butylphenyl-9,10-dihydroanthracene

Autor: Anita Coetzee

Publikováno v: Supramolecular Chemistry. 9:109-114

The host trans-9,10-dihydroxy-9,10-di-p-tert-butylphenyl-9,10-dihydroanthracene (DDTBDA) forms a 1:1 inclusion compound with methanol. The crystal structure, thermal analysis and kinetics of desolvation, using isothermal thermogravimetry is described

A quartz micro balance for measuring the kinetics of guest uptake from the vapour

Autor: Anita Coetzee, Luigi R. Nassimbeni, Klaus Achleitner

Publikováno v: Scopus-Elsevier

The design of a multiple probe quartz microbalance (QMB) for the study of guest-uptake in inclusion compounds is reported. The kinetics of inclusion of 1,3-dioxolane by 9,10-dihydroxy-9,10-diphenyl-9,10-dihydroanthracene is reported as an example of
