Abstract
A fully encapsulated Pt4 tetrahedron in an incomplete tetrahedron of 36 nickel atoms is present in [Ni36Pt4(CO)45]6− (1; see picture for the metal framework), which is obtained as an inseparable mixture with [Ni37Pt4(CO)46]6− (2) by reaction of [Ni6(CO)12]2− with K2[PtCl4]. 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.
