We present the results of an ab initio study of the relative stability of structural phases of GaN and InN materials at high pressures. Both the local density and generalized gradient approximations for the exchange-correlation potential have New Balance 990 Canada been used in the calculations. The wurtzite, New Balance 990 Black zinc-blende and rocksalt structures are considered. Comparisons with the available experimental data reveal a roughly better agreement with respect to previous calculations. In many cases, the generalized gradient approximation results are found to differ significantly from those of the local density approximation. A dichloromethane solution of the cationic carbonyl complex [IrCl2(CO)(PMe2Ph)3)][ClO4] reacts with aqueous KOH to give [IrCl2(CO2H)(PMe2Ph)3] which has been characterised spectroscopically. This CO2H compound is very much more basic and very much less acidic than [IrCl2(CO2H)(CO)(PMe2Ph)2). Tertiary amines will not New Balance Windbreaker 574 Canada deprotonate [IrCl2(CO2H)(PMe2Ph)3] while Li[N(SiMe3)2] leads to decarboxylation products trans, mer- and cis, mer-[IrHCl2(PMe2Ph)3]. The mechanisms of these reactions are considered and the hydroxycarbonyl complex is compared with its formato isomer which decarboxylates much less readily.
