Reaction of Tri(phenylethynyl)arsane and -stibane with Octacarbonyldicobalt; Crystal Structure of (Ph-CC)As2-CC-Ph)Co2(CO)6>2

The synthesis of tri(phenylethynyl)arsane (1) and -stibane (7) is discussed.Octacarbonyldicobalt reacts selectively with 1 or 7 to yield the η2-side-on co-ordinated phenylethynyl complexes (Ph-CC)nE2-CC-Ph)Co2(CO)6>3-n (E = As: n = 2: 3, n = 1: 4, n = 0: 5; E = Sb: n = 2: 8; n = 1: 9; n = 0: 10), which contain sterically hindered carbon-cobalt tetrahedrane cluster units. 3 gives upon heating 2-CC-Ph)Co2(CO)5>>2 (6) a compound containing a six-membered Co2As2C2 ring.All new compounds have been characterized by analytical and spectroscopic data (IR, 1H, 13C NMR), and (Ph-CC)As2-CC-Ph)Co2(CO)6>2 (4) by X-ray analysis.
