Abstract
Each of the title compounds, 8-methoxy-7,7-bis(triphenylphosphine-P)-8,9:10 ,11-di-muH-7-platina-nido-undecaborane dichloromethane hemisolvate, [Pt(CH1 4B10O)(C18H15P)(2)].0.5CH(2)Cl(2), (I), 8-isopropoxy-7,7-bis(triphenylphosp hine-P)-8,9:10,11-di-muH-7-platina-nido-undecaborane dichloromethane solvat e, [Pt(C3H18B10O)(C18H15P)(2)]. CH2Cl2, (II), and 9-isopropoxy-7,7-bis(trip henylphosphine-P)-8,9:10,11-di-muH-7-platina-nido-undecaborane dichlorometh ane solvate, [Pt(C3H18B10O)(C18H15P)(2)]. CH2Cl2, (III), has an 11-vertex n ido polyhedral skeleton, with the 7-platinum centre ligating to two exo-pol yhedral PPh3 groups and an alkoxy-substituted polyhedral borane ligand. Com pounds (II) and (III) are isomers. The Pt-B distances are in the range 2.21 4 (7)-2.303 (7) Angstrom for (I), 2.178 (16)-2.326 (16) Angstrom for (II) a nd 2.205 (6)-2.327 (6) Angstrom for (III).
