Bond lengths oxides

Several reviews have considered possible relationships between y( Pt P) and structural features of the complexes.Although there are reasonable correlationships with bond lengths, oxidation state, and trans influence, too detailed quantitative analysis is hazardous as illustrated by the results for [PtR(PR )3]. Koie etal. have demonstrated the correlation between /(PtP) in some Pt° and Pt complexes and the mutual polarizability from extended Hiickel MO calcula-tions. Relationships between structural features and /(i 5pjij y292,3oo,3i3) y( Pt C) in CH3, and cod derivatives, V( Pt H) in CH3 derivatives,... [Pg.551]

The stmctural parameters of ethylene oxide have been determined by microwave spectroscopy (34). Bond distances iu nm determined are as follows C—C, 0.1466 C—H, 0.1085 and C—O, 0.1431. The HCH bond angle is 116.6°, and the COC angle 61.64°. Recent ah initio studies usiug SCF, MP2, and CISD have predicted bond lengths that are very close to the experimental values (35,36). [Pg.452]

The computation of furoxans (l,2,5-oxadiazole-2-oxides) is very demanding. Very strong electron correlation effects hamper a proper treatment of this class of molecules. With respect to the geometric parameters, it is the endocyclic N—O bond that can be treated reliably either at the B3-LYP or at the MP4(SDQ) level [99MI1 ]. Table II demonstrates the problems associated with the exact determination of this bond length. [Pg.34]

Cation size can affect bond lengths in OsCl6 Os—Cl is 2.284 A and 2.303 A in the Ph4P and Bu4N salts, respectively. Oxidation, however, has a more significant effect, so that Os-Cl in (Ph4P)2OsCl6 is 2.332 A. [Pg.8]

They demonstrate the sensitivity of the Ru—N bond length to the trans-donor atom and also how when a multidentate ligand is involved bond lengths do not necessarily shorten on increasing the oxidation state. [Pg.51]

All of these probably have the A1C13 structure (unconfirmed for Rhl3) with bond lengths (EXAFS) of 2.337 A (Rh-Cl) [13] and 2.48 A (Rh-Br) [14]. Soluble chlorides and bromides are made by dissolving the oxide in the appropriate acid. [Pg.80]

Many of the compounds in higher oxidation states are reactive, and for moisture-sensitive solids that cannot be crystallized, some of the bond lengths quoted in Table 2.1 are from EXAFS measurements [24], Raman spectroscopy is likewise well suited to studying such reactive compounds, and vibrational data for halometallates are given in Table 2.2 trends illustrated include the decrease in frequency as the oxidation state of the metal decreases, and similarly a decrease in vibrational frequency, for a given oxidation state, with increasing mass of the halogen. [Pg.82]

There is a concomitant decrease in the length of the carbon-sulfur bonds in the thiirene series, but irregularity is apparent in the decrease of the carbon-sulfur bond in the thiirane series. Thus, r(CS) 19b carbon-sulfur bond lengths of 20a and its oxide (16a) are essentially identical. [Pg.387]
