which is also formed from the reaction of MeOH with [8,8-(PPh3)2-nido-8,7-PtCB9H10] (3). Both compounds have been characterised by single-crystal X-ray diffraction analysis and examined by NMR spectroscopy and have structures based on eleven-vertex nido-type geometries, with the metal centre and the heteroatoms in the adjacent (8)- and (7)-positions on the pentagonal open face.
