A fully encapsulated Pt 4 tetrahedron in an incomplete tetrahedron of 36 nickel atoms is present in [Ni 36 Pt 4 (CO) 45 ] 6− ( 1 ; see picture for the metal framework), which is obtained as an inseparable mixture with [Ni 37 Pt 4 (CO) 46 ] 6− ( 2 ) by reaction of [Ni 6 (CO) 12 ] 2− with K 2 [PtCl 4 ]. The trimethylbenzylammonium salts of 1 and 2 cocrystallize in a 1:1 ratio. The additional Ni atom of 2 caps the truncated vertex of 1 .
