title: Synthesis and X-ray crystal structure of an anionic heteronuclear metallamacrocyclic triangle.
abstract: trans-[Pt(C[triple bond]C(Ar)C[triple bond]CH)2(PMe3)2](Ar = C(6)Me(4)-3,4,5,6) (1) reacts with PPN[Au(acac)(2)](Hacac = acetylacetone; 1 : 1.16 molar ratio; PPN = (Ph3P)2N) to give PPN[(Au[Pt(PMe3)2]2)(mu-Ar(C[triple bond]C)2)3] (2) the crystal structure of which showed the anions as quasi equilateral triangles stacked parallel to each other through C-HAu interactions, resulting in channels of rhombic cross-section.
