  The reactions of 2-hydroxypyridine ligands with Re2Cl4(μ-dppm)2 (dppm=Ph2PCH2PPh2) that lead to 2-pyridonate complexes

  摘要：

  2-Hydroxypyridine (Hhp), 2-hydroxynicotinic acid (HnicOH) and 6-hydroxypicolinic acid (HpicOH) react with Re2Cl4(mu-dppm)(2) (dppm = Ph2PCH2PPh2) to afford the complexes Re-2(eta(2)-hp)Cl-3(mu-dppm)(2) (1), Re-2(eta(2)-HnicO)Cl-3(mu-dppm)(2) (2) and Re-2(mu-picO)(2)(mu-dppm)(2) (3). The identities of 1 and 2 have been established by single-crystal X-ray structure determinations (Re-Re distances of 2.2602(3) and 2.2539(3) Angstrom, respectively) and they are shown to have unsymmetrical structures with staggered rotational geometries and trans, cis coordination of the pair of mu-dppm ligands. The crystal of 2 that was used in the structure determination was found to be of composition 2Re(2)(eta(2)-HnicO)Cl-3(mu-dppm)(2) (.) Re2Cl6(mu-dppm)(2) (.) 2.906CH(2)Cl(2). The structure of Re2Cl6(mu-dppm)(2) in this crystal is compared with structures reported in the literature for other crystals that contain this edge-sharing bioctahedral dirhenium(III) complex.
