Abstract The reaction of two equivalents of K2PtCl4 with the hexaphosphine ligand system (Et2PCH2CH2)2PCH2P(CH2CH2PEt2)2, EHTP, quantitatively yields the diamagnetic dimer species, Pt2Cl2(eHTP)2+, 3. The single-crystal X-ray structure of the PF6− salt of 3 reveals a distorted square-planar environment about the metal atoms with the EHTP ligand adopting a symmetrical bischelating/bridging, partially closed-mode
