  1,2,3,4-Tetraphenyl-1,2-dihydrodiphosphetene 1 reacts with lithium or sodium naphthalenide to afford the corresponding dianionic salts 2 and 3. An X-ray crystal structure analysis shows that dianion 3 of general formula [(1)Na-2-(2)3(DME)(2), Na(DME)(3)] is a polymeric structure consisting of [(1)Na-2-(2)3(DME)(2)] units which are connected together through one sodium atom. Reaction of the dianionic lithium salt 2 with [Pt(COD)Cl-2] affords the 4[Li(2.2.1)](2) complex, after the addition of 2 equiv of (2.2.1) cryptate. The overall geometry around platinum in 4[Li(2.2.1)](2) can be described as distorted square planar, and only the diastereomer (1-R, 2-S, 3-R, 4-S) is formed. X-ray data indicate that no delocalization takes place within each platinadiphospholene unit and that complex 4[Li(2.2.1)](2) must be regarded as the coordination of two molecules of dianion 2 onto a Pt2+ center. Reaction of the dianionic sodium salt 3 with 1 equiv of [Pt(COD)Cl-2] produces the 4[Na(DME,Et2O)](2) complex which adopts a pseudotetrahedral geometry around platinum (theta between interplane angles = 35degrees), the two cationic units [Na(DME, Et2O)] being located along a C-2 axis. Four weak interactions exist between the sodium cations and the phosphorus atoms. Only the (1-S, 2-S, 3-S, 4-S) diastereomer is formed. Bond distances in the diphospholene units of 4[Na(DME,Et2O)](2) are close to that of dianion 3 indicating that, like in 4[Li(2.2.1)](2), the complex can be described as a platinum (+2) dianionic species.
