The element symbols within each formula are arranged according to a modified Hill system in which the order is metal(s), C, H and then any remaining symbols arranged alphabetically. Compounds containing two (or more) different metals appear twice (or more), being listed under each metal. Common ligand abbreviations which appear in the text have also been used in the index. These include acac (acetylacetone), bipy (2,2 -bipyridyl), diars [o-phenylenebis(dimethyl-arsine)], dien (diethylenetriamine), etc. [Pg.255]

The solubility properties of salen-type complexes can be tailored by employing substituents such as t-butyl and triphenylphosphonium-methyl (—CFl2PPh3+), with its associated chloride, in the aromatic rings.The stability constant for A,A -o-phenylenebis(salicylideneimine)-iron(III) in 80% (w/w) DMSO-water has been compared with stability constants for complexes of six metal ions with this ligand. [Pg.474]

This procedure is similar to that used for the synthesis of bis(dimethyl phosphito-P)[ethylenebis(diphenylphosphine)]platinum(Il).8 To a solution of bis(dimethyl hydrogen phosphite-i>)bis(dimethyl phosphito- )platinum(II) (0.976 g, 1.5 mmole) in benzene (50 mL) is added o-phenylenebis(dimethylarsine) 9 (0.441 g, 1.5 mmole). The solution is heated at reflux with stirring for 1 hour and then allowed to cool to room temperature. The colorless compound precipitates and is collected by suction filtration on a medium-porosity fritted glass. The complex is washed with benzene (two 5-mL portions) and then... [Pg.100]

The compound is very soluble in chloroform and dichloromethane and insoluble in benzene, diethyl ether, and ligroin. The H NMR spectrum shows a resonance for the methoxy groups at r 6.905 (3JpoCH = 12 Hz) with additional resonances from o-phenylenebis(dimethylarsine) centered at r 8.70 and 2.90. The complex forms the trimetallic compounds [ Pt[OP(OCH3)2] 2 [o-C6H4[As(CH3)2] 2 2M] (C104)2 [M = Cu, Co] on treatment with the appropriate metal perchlorate salt. [Pg.101]

In conclusion, this extreme importance of preassociation of reagents appears to be peculiar to the cobaltammine systems and may very well arise from some property of the N-H bond (27). Recent work on the substitution reactions of [Co diars2 Cl2]+ (diars = o-phenylenebis(dimethylarsine)) in methanol shows that, even in the case of the cis complex, there is absolutely no kinetic effect in isomerization, in... [Pg.16]

For cir (C ) complexes four v(MCl) are allowed in the IR spectra (2A, + Bt + B2) whereas for trans (Dih) complexes only one v(MCl) mode is allowed ( ) these complexes are considered to have the cis (C ) structure. [Pg.356]

The only recorded compound appears to be the complex with o-phenylenebis(dimethyl-arsine), PaCl5-xC6H4(AsMe2)2 (1 [Pg.1179]

The alkali metals Li and Na promote the dimerization of the complex N,N -o phenylenebis(salicylideneiminato)nickel(II), [Ni(salophen)], by means of the reductive coupling of two imino groups between two Ni(salophen) molecules (Scheme 29).2352... [Pg.197]
