Synthesis and structure of tetraphenylantimony 1-adamantanecarboxylate and triphenylantimony bis(1-adamantanecarboxylate)
摘要:
Reaction of pentaphenylantimony with triphenylantimony bis(1-adamantylcarboxylate) yielded the solvate of tetraphenylantimony 1-adamantylcarboxylate with benzene. Triphenylantimony bis(1-adamantylcarboxylate) was prepared from triphenylantimony and 1-adamantylcarboxylic acid in the presence of hydrogen peroxide in ether. X-ray studies showed that in the first and in the second product antimony atom has the distorted trigonal bipyramide coordination (OSbO and CSbO trans-angles are 179.42A degrees and 174.58A degrees, respectively). Sb-O interatomic distances are 2.154 and 2.202 , respectively. The carbonyl group oxygen atom is coordinated with the central atom, Sba <-O interatomic distances are 2.570 and 3.396 , respectively.
