The compound > is a complex of a macropolyhedral 16-vertex borane ligand based on the structure of an as yet unknown B6-B10 conjuncto-borane; it is the first example of a contiguous 17-vertex cluster species, and has a number of other interesting features.

Thermolysis of in refluxing toluene solution gives the known yellow 14-vertex diplatinaborane plus two novel 17-vertex cluster compounds, viz. the green triplatinaborane (1) and the red monoplatinaborane (2).Crystals of (1), as its 1:1 solvate with CH2Cl2, are monoclinic, space group P21/c, with a = 1 249.0 (3), b = 3 732.6 (8), c = 1 072.0 (2) pm, β = 104.92 (2) deg, and Z = 4; the structure was refined using 4 802 independent Fo with I > 2?(I) to a final R = 0.049, R' = 0.045.Crystals of (2) are also monoclinic, space group P21, with a = 992.7 (3), b = 1 067.2 (2), c = 1 378.7 (3) pm, β = 95.08 (2) deg, and Z = 2; the structure was refined using 1 992 independent Fo with I > 2?(I) to a final R = 0.0216, R' = 0.0248.These two new macropolyhedral boranes have been further characterized by multielement, multiple resonance, and multidimensional n.m.r. spectroscopy.The metal-to-borane bonding is discussed in terms of the 'non-conical' nature of the platinum contribution to the cluster bonding schemes.
