Abstract
The crystal and molecular structures of Os-III(tpy)(Cl)(3) (1) (tpy=2,2':6' ,2 "-terpyridine) and (PPN)[Os-III(Tp)(Cl)(3)] (2) (PPN+=bis-(triphenylphos phoranylidene) ammonium cation, Tp=hydrido tris(1-pyrazolyl)borate anion) a re reported. In trans-Os-III(tpy)(Cl)(3) (1) Os-Cl bond lengths are in the range 2.3604(10)-2.3833(9) Angstrom. In (PPN)[Os-III(Tp)(Cl)(3)] (2) Os-Cl band lengths are in the range 2.3789(19)-2.4082(17) Angstrom. These bond le ngths are consistent with Os-III as compared with similar values in chloro- containing Os compounds found in the literature. (C) 1999 Elsevier Science Ltd. All rights reserved.
