Thermolysis of (1) in C2D2Cl4 solution gives the new, pale yellow air-stable compound (2) in 80 percent yield.Crystals of the CH2Cl2 hemisolvate of (2) are monoclinic, space group P21/c, with a = 1130.0(3), b = 1292.2(3), c = 2424.0(5) pm, β = 94.15(2) degree, and Z = 4; the molecular structure was refined to R = 0.0399, R' = 0.0454.The detailed n.m.r. behaviour of compound (2) together with data for previously reported rhodium and iridium analogues permits the location of the substituent site on previously unconfirmed and thence provides information on mechanistic pathways for the formation of these and related metallaboranes.Detailed n.m.r. data for the non-metalla analogues - and previously unassigned - provide information on their mechanism of formation and a comparison with the metallaborane analogues.The n.m.r. work includes extensive use of - COSY and - COSY experiments and establishes general points.
