- Forty-four children were studied to compare the pathogenesis of fever in cerebral malaria, uncomplicated malaria and measles at the Eldoret District Hospital (EDH). A control group of normal children was used. The three patient groups were studied for three consecutive days measuring skin and core temperature three-times a day using the Liquid Crystal Device (LCD) thermometer. A statistical analysis of the results within and between the groups was carried out for core and skin temperature over the study period. No statistical differences were found between the groups for either the skin or the core temperature, but a significant statistical difference was demonstrated between the core and the skin temperature for all of the groups for each of the three days. No statistical difference was found when the differences between the core and skin temperature were compared between cerebral malaria and uncomplicated malaria. The possible roles of fever in morbidity and mortality are discussed, with special reference to cerebral malaria.

- The labilised clusters [Os3(CO)11–nLn(NCMe)][n= 1, L = PMe3 or CNBut; n= 2, L = P(OMe)3] have been prepared. The reaction of [Os3(CO)11 –nLn(NCMe)] or [Os3(CO)10{P(OMe)3}(NCMe)] with either [Os3(CO)11(PH3)] or [Os3(µ-H)(CO)10(µ-PH2)] led to the formation of the phosphide-bridged clusters [Os6(µ-H)(CO)21{P(OMe)3}(µ-PH2)], [Os6(µ-H)(CO)21(PMe3)(µ-PH2)], [Os6(µ-H)(CO)21(CNBut)(µ-PH2)], [Os6(µ-H)(CO)20{P(OMe)3}2(µ-PH 2)] and the corresponding phosphinidene-bridged clusters [Os6(µ-H)2-(CO)21 –nLn(µ3-PH)][n= 1, L = CNBut; n= 2, L = P(OMe)3] in good yield. The Os6 clusters have been fully characterised on the basis of their spectroscopic data and the molecular structures of three have been established by single-crystal X-ray analysis. The structures of [Os6(µ-H)(CO)20{P(OMe)3}2(µ-PH 2)] and [Os6(µ-H)2(CO)19{P(OMe)3}2(µ3-PH)] differ from those of previously studied hexanuclear phosphide- and phosphinidene-bridged clusters; this difference is attributed to the steric influence of the relatively bulky phosphite ligands. Proton and phosphorus NMR spectroscopy indicate that both these clusters exist in two isomeric forms in solution.

Systematic Synthesis of Hexanuclear Phosphido-bridged Osmium Clusters; Crystal and Molecular Structure of HOs6(CO)22PH2

Tidskriftsartikel (refereegranskat)abstract
- The phosphido-bridged cluster [Os6(µ-H)(CO)22(µ-PH2)] and the corresponding phosphinidene-bridged cluster [Os6(µ-H)2(CO)21(µ-PH)] have been prepared from the reaction of [Os3(CO)11(PH3)] with [Os3(CO)11(NCMe)] in toluene. In a similar reaction, [Os6(µ-H)(CO)21(NCMe)(µ-PH2)] has been prepared from the reaction of [Os3(CO)11(PH3)] with [Os3(CO)10(NCMe)2]. The two Os6 clusters have been fully characterized on the basis of their spectroscopic data and, in the case of [Os6(µ-H)(CO)22(µ-PH2)], by single-crystal X-ray analysis. In both compounds, two Os3 triangles are linked by a PH2 group which is terminally bound to each triangle. Thermolysis of [Os6(µ-H)(CO)22(µ-PH2)] and [Os6(µ-H)(CO)21(NCMe)(µ-PH2)] leads to the formation of [Os6(µ6-P)(CO)18]– and [Os6(µ-H)(µ6-P)(CO)18], respectively.

The Crystal and Molecular Structure of HOs6(CO)21(NCMe)PH2

Tidskriftsartikel (refereegranskat)abstract
- The crystal structure of the phosphide-bridged cluster [Os6(μ-H)(CO)12(NCMe)(μ-PH2)] 4 has been determined. The cluster consists of two Os3 triangles which are linked by a PH2 moiety which is terminally bound to each triangle. The acetonitrile ligand is axially coordinated and the hydride bridges the Os---Os edge to which the phosphide moiety and the acetonitrile are coordinated. The molecular structure of 4 resembles those of the related clusters [Os6(μ-H)(CO)22(μ-PH2)] 1 and [Os6(μ-H)(CO)21(CNBut)(μ-PH2)] 2 although the dihedral angles between the two osmium triangles vary for 1, 2 and 4. The relative orientation of the two linked metal triangles in 4 (as well as 1 and 2) differs from that of the phosphite-substituted analogue [Os6(μ-H)(CO)20{P(OMe)3}2(μ-PH2)]3; this difference is attributed to steric factors.
