Nie Y, Hu CH, Li X, Yong W, Dou JM, Sun J, Jin RS, Zheng PJ: Three monoalkoxy-substituted nido-platinaboranes: [(PPh3) 2PtB10H11-8-(OCH3)], [(PPh3) 2PtB10H11-8-[OCH-(CH3) 2]] and [(PPh3) 2PtB10H10-9-[OCH (CH3) 2]]. Acta Crystallogr C. 2001 Aug;57(Pt 8):897-9. Epub 2001 Aug 9.
Each of the title compounds, 8-methoxy-7,7-bis (triphenylphosphine-P)-8,9:10,11-di-muH-7-platina-nido-un decaborane dichloromethane hemisolvate, [Pt (CH (14) B (10) O)(C (18) H (15) P)(2)].0.5CH (2) Cl (2), (I), 8-isopropoxy-7,7-bis (triphenylphosphine-P)-8,9:10,11-di-muH-7-platina-nido -undecaborane dichloromethane solvate, [Pt (C (3) H (18) B (10) O)(C (18) H (15) P)(2)].CH (2) Cl (2), (II), and 9-isopropoxy-7,7-bis (triphenylphosphine-P)-8,9:10,11-di-muH-7-platina-nido -undecaborane dichloromethane solvate, [Pt (C (3) H (18) B (10) O)(C (18) H (15) P)(2)].CH (2) Cl (2), (III), has an 11-vertex nido polyhedral skeleton, with the 7-platinum centre ligating to two exo-polyhedral PPh (3) groups and an alkoxy-substituted polyhedral borane ligand. Compounds (II) and (III) are isomers. The Pt-B distances are in the range 2.214 (7)-2.303 (7) A for (I), 2.178 (16)-2.326 (16) A for (II) and 2.205 (6)-2.327 (6) A for (III). |
