Heterometallic Ni-Pt Chini-Type Carbonyl Clusters: An Example of Molecular Random Alloy Clusters.

ABSTRACT: The direct reactions of homometallic [Ni₆(CO)₁₂]^2- and [Pt₆(CO)₁₂]^2- Chini carbonyl clusters result in heterometallic Ni-Pt Chini-type clusters of the general formula [Pt_6-xNi_x(CO)₁₂]^2- (x = 0-6). Their molecular structures have been determined by single-crystal X-ray diffraction (SC-XRD), showing a common octahedral (staggered, D_3d) structure analogous to that of [Ni₆(CO)₁₂]^2-, whereas [Pt₆(CO)₁₂]^2- displays a trigonal-prismatic (eclipsed, D_3h) structure. This structural change after replacing one single Pt with Ni may be classified as an alloyin
