Potassium diplatinum(II) tetrakispyrophosphite (abbreviated as [Pt2(pop)44−) is the inorganic compound with the formula K4[Pt2(HO2POPO2H)4]. It is a water-soluble yellow salt. The compound has a long-lived, strongly luminescent excited state, with an emission maximum at ~510 nm and a lifetime near 10 μs. [1]
The complex is prepared by heating a mixture of potassium tetrachloroplatinate and phosphorous acid: [2]
Several quat salt derivatives are known. [3] [4]
The anion reacts with boron trifluoride to give the BF2-capped complex [Pt2(P2PO5)4(BF2)84-. [5]
The compound reacts with halogens to give Pt(III) dimers:
With substoichiometric halogen, linear chain compounds result.
The pair of square-planar platinum(II) centers are bridged by four pyrophosphito (HO(O)POP(O)OH2-) ligands. The ligands interact via hydrogen bonds between the POH and P=O group. The Pt---Pt separation is 293 pm for the dihydrate. In the Pt(III) dichloride, the Pt-Pt distance is 270 pm, indicating Pt-Pt bonding. [1]
