[Rh10As(CO)22]3-. Example of encapsulation of arsenic by transition-metal carbonyl clusters as illustrated by the structural study of the benzyltriethylammonium salt

The reaction of Rh(CO)2acac and alkali carboxylates in a glyme solvent with Ph3As under ～300 atm of carbon monoxide and hydrogen resulted in the isolation of [PhCH2N(C2H5)3]3[Rh 10As(CO)22]·C4H8O. The complex has been characterized via a complete three-dimensional X-ray diffraction study. The complex crystallizes in the primitive monoclinic space group P21/n, with a = 14.785 (2) A?, b = 22.495 (7) A?, c = 23.083 (5) A?, β = 95.45 (1)°, V = 7642.3 A?3, and δ(calcd) = 2.059 g/cm3. The structure was solved by direct methods and refined by difference-Fourier and least-squares techniques. All nonhydrogen atoms have been located and refined; final discrepancy indices are RF = 5.4% and RwF = 6.0% for all 3093 symmetry-independent reflections in the range of 0.5° ≤ 20 ≤ 45°. The structure consists of a bicapped square antiprism of rhodium atoms with the arsenic atom in its center. Rhodium-rhodium contacts are in the range 2.869-3.120 A? with arsenic-rhodium contacts of 2.502 and 3.008 A? for the metal atoms on the prism and the capped corner, respectively. Average values for the rhodium-carbon and carbon-oxygen distances are in the normal range, 1.83 and 1.16 A?, respectively, for the terminal carbonyls. There are one set of symmetrical and another of asymmetrical bridging carbonyls with Rh-C = 1.99 A? and C-O = 1.21 A? for the former set and Rh-C = 2.222 and 1.95 A? and C-O = 1.20 A? for the latter one, as is usual in this situation. High-pressure infrared studies show the cluster is stable under 537 atm of CO-H2 (1:1 ratio) up to 150°C, but it reacts under 1000 atm, yielding [Rh(CO)4]- and [Rh9As(CO)21]2-. The reaction of these two anions to form the initial anion has also been established.
