Summary
The reactions of 2,2′-biquinoline(biq) with M(PhCN)2X2 (M=Pd; X=Cl or Br; M=Pt, X=Cl, Br or I), K2PtCl4 and RhCl3·3H2O and of 2-(2′-pyridyl)quinoline (pq) with K2PtCl4 and RhCl3·3H2O have been investigated. The isolated complexescis-[Pd(biq)X2] (X=Cl or Br),cis-[Pt(biq)Cl2],cis-[Pt(biq)Cl2]·H2O,trans-[Pt(biq)2Br2]·5H2O, [Pt3(biq)2I6],mer-[Rh(biq)Cl3-(H2O)] andmer-[Rh(pq)Cl3(H2O)] have been characterized by elemental analyses, conductivity measurements, i.r., electronic, and1H n.m.r. spectra. The reaction of pq with K2PtCl4 in 1M H2SO4 gave the salt 2-(2′-pyridyl) quinolinium tetrachloroplatinate(II) pentahydrate, (pqH)2[PtCl4]·5H2O; when the reaction was carried out in aqueous acetone,cis-[Pt(pq)Cl2] was obtained. A new method for the synthesis ofcis-[Rh(biq)2X2]X (X=Cl or Br) is described; both compounds have been further characterized by1H n.m.r.
