| Abstract: | Structure and Constitution of Dichloro(tetraalkylcyclobutadiene)platinum(II) Complexes Hexachloroplatinic acid reacts in n-butanol with alkylsubstituted acetylenes RC≡CR (R = Me, Et) to give PtCl2(C4R4)] (R = Me ( 1 ), R = Et ( 2 )). The X-ray structure analysis of 1 (C2/m; a = 1 370.3(2), b = 1 128.3(1), c = 691.21(7) pm, β = 96.10(1)α; Z = 4) shows that 1 is monomeric and not dimeric as was described in the literature. Furthermore, 1 and 2 were extensively studied by i.r., Raman, and n.m.r. spectroscopical investigations. |
