==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. 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
