✦ Synopsis

group P1 (No. 2), a = 18.711(4), b = 16.379(3), c = 11.724(2) A, a = Z = 1, eCalcd = 3.147 g ~m -~, F(000) = 2694, R = 0.0938 for 3537 reflections with I/u(I) z 3.0 corrected for absorption [~(Mo,.) = 201.6 cm-'1.

The only crystals which could be obtained diffracted rather weakly due to marked disorder of the [PPN] counterions. Relatively high thermal parameters for Os(9) and Hg appear to be due to slight disorder of the cluster dianion, which could not be resolved. Nonetheless, the structural features of the cluster are well established. Further details of the crystal structure investigations are available on request from the Director of the Cambridge Crystallographic Data Centre, University Chemical Laboratory, Lensfield Road, Cambridge CB2 IEW (UK), on quoting the full journal citation.

Adam'ZltyZ- or homoadamantyl-derived N-bri&ehead amides are converted in high yields into hydrocarbon derivatives on prolonged ref7,ux in ethanol and 50% sulphuric acid (I:1 by volwne). This process probably involves A AL1 hydrolysis to the tertiary carboniwn ion, followed by hydride abstraction fro
