Bond distances for

X-ray crystallographic analysis of the sodium thiosulfate pentahydrate [10102-17-7] crystal indicates a tetrahedral stmcture for the thiosulfate ion. The S—S bond distance is 197 pm the S—O bond distance is 148 pm (5). Neutron diffraction of a barium thiosulfate monohydrate [7787-40-8] crystal confirms the tetrahedral stmcture and bond distances for the thiosulfate ion (6).

Bond distances for some important bond types are given in Table 1.5. As can be seen in this table, carbon bonds are shortened by increasing s character. This is most often explained by the fact that, as the percentage of s character in a hybrid orbital increases, the orbital becomes more like an s orbital, and hence is held more tightly by the nucleus than an orbital with less s character. However, other explanations have also been offered (see p. 37), and the matter is not completely settled.

Diketonate cobalt(III) complexes with alkyl peroxo adducts have been prepared recently and characterized structurally, and their value in hydrocarbon oxidation and olefin epoxidation examined.980 Compounds Co(acac) 2(L) (O O / - B u) with L = py, 4-Mepy and 1-Meim, as well as the analog of the first with dibenzoylmethane as the diketone, were prepared. A distorted octahedral geometry with the monodentates cis is consistently observed, and the Co—O bond distance for the peroxo ligand lies between 1.860(3) A and 1.879(2) A. 

Certain general trends in M-0 bond distances can be correlated with bond multiplicity and the degree of oxygen-to-metal TT-bonding. A comparison of M-0 bond distances for structurally related compounds having a M, (p3-X) 2 (p2-X) Xx 0 unit is given in Table II. For M = Mo and W in closely related compounds, differences in M-L distance are negligible. 

In one pair of chains the rhomboidal cluster units have five Mo-Mo bonds of nearly equal length (regular units), and in the other pair the (distorted) rhomboidal units have three short and two long Mo-Mo bonds. Figure 3 shows how these rhomboidal units are bound together within the infinite chains. A comparison of Mo-Mo and selected Mo-0 bond distances for the regular and distorted cluster units is given in Table III. 

What is the region of bond distances for hypervalent bonds of chalcogens Bond orders of hypervalent 3c-4e are typically around 0.5. A bond distance with a bond order of 0.5 is predicted to be 0.18 A longer than that with a bond order of 1.0.16...
