Reactions of cis-di-isocyanidebis(perfluorophenyl)gold(III) complexes with hydrazines. Crystal and molecular structure of cis-[Au{C(NHC6H4Me-p)=N–N(Ph)C(NHC6H4Me-p)}(C6F5)2]
Abstract
Addition of CNR (R = Ph or p-tolyl) to solutions of cis-[Au(C6F5)2(OEt2)2]ClO4 leads to cis-[Au(C6F5)2(CNR)2ClO4, which reacts (a) with NHPhNHPh to give the cationic complexes [A[graphic omitted](NHR)}(C6F5)2]ClO4, which readily undergo deprotonation to form [A[graphic omitted](NHR)}(C6F5)2], and (b) with NH2NHR′(R′= H or Ph) to give [A[graphic omitted](NHR)}(C6F5)2]. The structure of [A[graphic omitted]-(NHC6H4Me-p)}(C6F5)2] has been determined by X-ray diffraction [space group P21/c, with a= 12.230(2), b= 20.276(3), c= 13.123(2)Å, β= 101.21(2)°, R= 0.036 for 5 822 reflections].
