Structurally characterised 17-vertex [(PMe2Ph)(2)PtB16H17Me] 3 is obtained, albeit in low yield, by platination of 16-vertex B16H20 1 using [PtMe2(PMe2Ph)(2)] under mild conditions. Platination has occurred on the {B-10} subcluster of 1, interesting in that B16H20 itself deprotonates on the {B-8} subcluster: the reference 16-vertex [B16H19](-) anion 1a, prepared by deprotonation of 1 with 1,8-bis(dimethylamino) naphthalene, is also structurally characterised. [PtMe2(PMe2Ph)(2)] with 14-vertex B14H18 2 similarly gives a low yield of 15-vertex [(PMe2Ph)(2)PtB14H16] 5, of formulation and structure substantiated by DFT calculations.

Byly strukturně charakterisovány nové 17- a 15-vrcholové komplexy platiny, [(PMe2Ph)2PtB16H17Me] a [(PMe2Ph)2PtB14H18] .
