Structure and Constitution of Dichloro(tetraalkylcyclobutadiene)platinum(II) ComplexesHexachloroplatinic 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.
Notes:
Hexachloroplatin(IV)-säure reagiert in n-Butanol mit alkylsubstituierten Acetylenen RC≡CR (R = Me, Et) zu Platincyclobutadien-Komplexen [PtCl2(C4R4)] (R = Me (1), R = Et (2)). Die Röntgeneinkristallstrukturanalyse von 1 (C2/m; a = 1 370,3(2), b = 1 128,3(1), c = 691,21(7) pm, β = 96 10(1)°; Z = 4) belegt, daß 1 monomer und nicht - wie bisher beschrieben - dimer aufgebaut ist. Desweiteren sind 1 und 2 umfassend durch IR-, Raman- und NMR-spektroskopische Untersuchungen charakterisiert.
