Tetrakis(triphenylphosphine)platinum(0) is the chemical compound with the formula Pt(P(C6H5)3)4, often abbreviated Pt(PPh3)4. The bright yellow compound is used as a precursor to other platinum complexes.〔Safety Data Sheet http://www.alfa.com/content/msds/english/10549.pdf〕
==Structure and behavior==
The molecule is tetrahedral, with point group symmetry of Td, as expected for a four-coordinate metal complex of a metal with the d10 configuration.〔Miessler, Gary L., and Donald A. Tarr. Inorganic Chemistry. 3rd ed. Upper Saddle River, NJ: Pearson Prentice Hall, 2004.〕 Even though this complex follows the 18 electron rule, it dissociates triphenylphosphine in solution to give the 16e derivative containing only three PPh3 ligands:
:Pt(PPh3)4 → Pt(PPh3)3 + PPh3
