Synthesis, crystal structure and Raman spectrum of K₂[(Pt₂)(HPO₄)₄(H₂O)₂] containing (Pt₂)⁶⁺ions

Abstract

In the crystal structure of the acid platinum phosphate dipotassium di-μ-hydrogenphosphato-bis­[aqua­platinum(III)](Pt—Pt), K2[Pt2(HPO4)4(H2O)2], the (Pt2)6+ dumbbells within the paddle-wheel complex show Pt—Pt distances of 2.4944 (5) and 2.4892 (5) Å. The pottassium ions are seven-fold coordinated by hydrogenphosphate groups. In the crystal, O—H⋯O hydrogen bonds help to establish the packing. The Raman spectrum was recorded.

Synthesis, crystal structure, and vibrational study of K2Cu(HPO4)2·6H2O: A new metal hydrogenphosphate compound

“…The distance corresponding to the PeOH bond in HPO 4 was 1.478(3) Å (Table 3). This value is, in fact, comparable to the ones previously reported for PeOH in the literature [11,12].…”

Direct intercalation of cisplatin into zirconium phosphate nanoplatelets for potential cancer nanotherapy

“…3.25 Å, too long for this kind of complex (experimental Pt-O bond lengths in Pt phosphate complexes are 1.96 – 2.09 Å). 46, 47 In contrast, the alternative crosslinked structure can be produced where the Pt complex is coordinated with a phosphate group from one layer and another phosphate from the adjacent layer. In addition, monoadducts between the platinum complex and the layers can also be formed, where one of the chlorine ligands of cisplatin is substituted by a water molecule and the other by a phosphate group of the ZrP layer.…”

The first molecular paddlewheel platinum(III) acetate complex Pt2(μ-OOCMe)4(O3SMe)2

“…A number of platinum(III) paddlewheel complexes with sulfate, phosphate, amidate and acetate bridges have been documented as anionic [1][2][3][4][5] or cationic [6][7][8][9] 195 Pt NMR spectrum tetra-μ-acetate-bridged Pt(III) species in solution [Pt 2 (μ-OCOCMe) 4 (OCOCMe) 2 ] [8].…”

“…DFT analysis with the exchange-correlation potential PBE1PBE in SDD basis revealed the electron configuration of the "metallic" moiety as σ 2 π 4 δ 2 δ* 2 π* 4 with Pt-Pt σ-bonding.A number of platinum(III) paddlewheel complexes with sulfate, phosphate, amidate and acetate bridges have been documented as anionic [1][2][3][4][5] or cationic [6-9] species. The neutral platinum(III) paddlewheel complexes are rather uncommon.…”
