Structural variations induced by changes in oxidation state and their role in electron transfer. Crystal and molecular structures of cis-(Ru(bpy)/sub 2/Cl/sub 2/) x 3. 5H/sub 2/O and cis-(Ru(bpy)/sub 2/Cl/sub 2/)Cl x 2H/sub 2/O
The results of an X-ray crystallographic study are reported on the hydrates cis-(Ru/sup II/(bpy)/sub 2/Cl/sub 2/) x 3.5H/sub 2/O and cis-(Ru/sup III/(bpy)/sub 2/Cl/sub 2/)Cl x 2H/sub 2/O (bpy is 2,2'-bipyridine, C/sub 10/H/sub 8/N/sub 2/). The Ru(II) complex crystallizes the monoclinic space group C2/c with four molecules in a cell of dimensions a = 18.248 (14) A, b = 13.146 (5) A, c = 10.792 (4) A, and ..beta.. = 119.49 (5)/sup 0/ and was refined to a final value of the weighted R factor of 0.031 based on 1912 independent observations. The Ru(III) complex crystallizes in the triclinic space group P1 with two molecules in a cell of dimensions a = 7.042 (3) A, b = 13.000 (5) A, c = 12.321 (3) A, ..cap alpha.. = 89.93 (2)/sup 0/, ..beta.. = 100.62 (2)/sup 0/, and ..gamma.. = 92.23 (3)/sup 0/ and was refined to a weighted R factor of 0.033 based on 2104 independent observations. In terms of intramolecular structure, there is a significant shortening (0.10 A) of the Ru-Cl bond upon oxidation and a slighter increase (0.04 A) in the Ru-N distances trans to the Ru-Cl bonds. 51 references, 2 figures, 6 tables.
