The reactions of ReH4(hq)(PPh3)2, where hq represents the monoanion of 2-hydroxyquinoline, with monodentate phosphines afford the seven-coordinate complexes ReH2(hq)(PPh3)2(PR3) (PR3 = PMe3 (1), PMe2Ph (2), PMePh2 (3), PPh3 (4), and PHPh2 (5)) which have been shown to possess pentagonal bipyramidal structures on the basis of X-ray crystal structure determinations of 1, 4, and 5. The unique PR3 ligand occupies the pentagonal plane in the case of 1 and 5. The reactions of 4 with PMe3 and PHPh2 lead to substitution of one of the PPh3 ligands and the formation of 1 and 5, respectively. The mild thermolysis of solutions of 4 in refluxing benzene affords the diphenyphosphine complex 5, along with some decomposition of 4 and the release of free PPh3; when this reaction is carried out in C6D6, the released PPh3 is found to contain the isotopomers PPh3-d0 through PPh3-d6 with the deuteration taking place only in the ortho positions.

The hydride reacted with 2,6-dimethylbenzenethiol in toluene to give a complex of stoichiometry 1.A crystal structure showed a trigonal-bipyramidal geometry about the Re with an agostic interaction to a thiolate methyl occupying an apical site, trans to the PPh3 ligand.Complex 1 reacts rapidly with MeCN to give the known 2 and with t-BuNC to form 3.The crystal structure of 3 showed trigonal-pyramidal geometry about the Re with asymmetric co-ordination of the isocyanide ligands and an unusual configuration for the thiolate aromatic groups.The reactions of the hydrides and with 2,4,6-triisopropyl-, 2,6-dimethoxy-benzenethiol and tris(2-sulfanylphenyl)phosphine were also studied.With HSC6H2(i-Pr)3-2,4,6 the dinitrogen complex 4 was formed and its structure determined.The preparations and structures of the complexes , 3(PPh3)> and (PPh3)> are also discussed.An alternative convenient route to (+) from is presented.
