The [Sn (sub)9 Pt (sub)2 (PPh (sub)3)] (super)2- and [Sn (sub)9 Ni (sub)2 (CO)] (super)3- complexes: two markedly different Sn (sub)9 M (sub)2 L transition metal zintl ion clusters and their dynamic behavior

Research has been conducted on the metalated polystannides. The synthesis, structures, properties and the solution dynamics of these complexes have been investigated and the detail are described.
