The Crystal Structure of (1, 1′‐ferrocenediyl)diphenylsilane

Abstract

E X 4 4QD, (,reat Uritaiii (12 V I I I 76)Summary. The crystal structurc of (1, 1'-fcrrocenediy1)diphcnylsilane Iias been determined from analysis of photographic X-ray data. The crystal system is orthorhoinbic, a = 14.18 (2)

The synthesis and structure of

“…Both the cyclopentadienyl rings are planar within experimental error, and, as has been previously established (20), ring ban$ to substituted atoms (1.435 (5) The crystal structure of a related [llferrocenophane I d has been determined (21). The general features of the two structures are very similar and are tabulated in Table 5.…”

“…The general features of the two structures are very similar and are tabulated in Table 5. The strain in the compounds is mainly reflected in the large value of P. Other (11) A (20). In a similar molecule where a SiMe2 group (essentially tetrahedral) bridges two Cp rings which are separated by two Fe atoms (and bridging carbonyl groups) the Si-Cp distances seem to be longer at 1.876 (7) A (21), although they are still within the normal Si-C range.…”

“…I : A mixture of 1.1'-bis(trimethylstannyl)ferrocene (1.41 g. 2.8 mmol) and dimethyltin dichloride (1.3 g. 5.9 mmol) was heated at 130 'C for 3 h Trimethyltin chloride was removed from the equilibrium by sublimation onto a cooling finger (15 bis(trtmethylsily1)mercury (0.47 g, 1.3 mmol) was added in one portion. The mixture was stirred at room temperature for 5 h. The toluene was then removed in vacuo and the residue was dissolved in pentane.…”
