TETRAKIS-(ETA(1)-1-PHENYL-3-NORMOHEXYLTRI AZENIDO)PLATINUM(IV), 1ST HOMOLEPTIC ARYLALKYLTRIAZENIDOPLATINUM(IV) COMPLEX

The first homoleptic tetrakis(arylalkyltriazenido) derivative of plati num, [C6H5NNN(CH2)5CH3]4Pt (3), has been prepared by reacting platinum tetrachloride with 1-phenyl-3-n-hexyltriazene and n-butyllithium in TH F. The readily soluble, yellow complex, stable towards air and water, has been characterized by single cristal x-ray cristallography and Pt- 195 NMR spectroscopy. Compound 3 crystallizes in the triclinic space g roup P1BAR (a = 1090.3(3) pm, b = 1081.1(2) pm, c = 1174.4(2) pm, alph a = 93.86(1)-degrees, beta = 108.07(2)-degrees, gamma = 99.00(2), V = 1.289(1) nm3, Z = 1 and R/R(w) = 0.038/0.035). The thermo- and photoch emical decomposition of the complex was investigated by DSC- and UV-me asurements.
