C. Callaghan et al., (Phosphacyclopentadienyl)indium(I) derivatives: Synthesis and X-ray crystal structure of [In(eta(5)-P3C2Bu2t)], ORGANOMETAL, 18(4), 1999, pp. 793-795
Go-condensation of indium vapor and tertbutylphosphaethyne at 77 K yields t
wo new, volatile In(I) complexes: [In(eta(5)-P3C2Bu2t)] (1) and [In(eta(5)-
P2C3Bu3t)] (2). A single-crystal X-ray diffraction experiment on I reveals
a discrete molecular structure, involving half-sandwich coordination of the
P3C2Bu2t ring around the indium center. 1 may be independently prepared by
treating InI with the newly synthesized, base-free ligand salt K(P3C2Bu2t)
