They display the considerable trans-influence of hydride and aryl groups (the Pt-Cl bond lengths should be compared with the value of c. 2.31 A in PtCl4 ). The Pt-P bond lengths are more insensitive to the phosphine, but by synthesis of ds-Pt(PR3)(PR3)Cl2 [150] complexes, it has been possible to study the effect of electron-withdrawing substituents on the Pt-P bond, as well as on the trans-influence of the phosphine (Figure 3.94).

Table 4.15 summarizes optimized bond lengths and NBO Lewis-like structures for 15 saturated normal-valent H MMH compounds (M = W-Pt) as well as corresponding hydrides of hypovalent Ta for comparison. The accuracy of the localized Lewis-like description (as measured by %pf) is found to be reasonably high both for normal-valent and for hypovalent species, typically >98% of the valence-shell density and >99.5% of the total density. 

Figure 4.23 graphically displays the metal-metal bond lengths (cf. Table 4.15) and their dependences on the formal bond order of the Lewis-like formula. These plots all show the expected decrease of mm with increasing bond order, but with somewhat different rates of decrease for different metal atoms. Thus, the multiplebonding of the Lewis-like picture readily accounts for the variations of metal-metal bond length in these hydrides.
