By reaction of [NBu4]2[Pt2(μC6F 5)2(C6F5)4] with 1,8-naphthyridine (napy), [NBu4][Pt(C6F5)3(napy)] (1) is obtained. This compound reacts with cis-[Pt(C6F5)2(THF)2] to give the dinuclear derivative [NBu4][Pt2(μ-napy)(μ-C6F 2)-(C6F5)4] (2). The reaction of several HX species with 2 results in the substitution of the bridging C6F5 by other ligands (X) such as OH (3), Cl (4), Br (5), I (6), and SPh (7), maintaining in all cases the naphthyridine bridging ligand. The structure of 3 was determined by single-crystal X-ray diffraction. The compound crystallizes in the monoclinic system, space group P21 /n, with a = 12.022(2) A?, b = 16.677(3) A?, c = 27.154(5) A?, β= 98.58(3)°, V = 5383.2(16) A?3, and Z = 4. The structure was refined to residuals of R = 0.0488 and Rw = 0.0547. The complex consists of two square-planar platinum(II) fragments sharing a naphthyridine and OH bridging ligands, which are in cis positions. The short Pt-Pt distance [3.008(1) A?] seems to be a consequence of the bridging ligands.
