Five zirconium complexes containing the 3-cyanopentane-2,4-dionate and 2-cyano-1-phenylbutane-1,3-dionate ligands (L) have been prepared: [ZrCl2(C6H6NO2)2], [ZrCl2(C11H8NO2)2], [ZrCl(C6H6NO2)3], [Zr(C6H6NO2)4], and [Zr(η-C5H5)(C6H6NO2)3]. Infrared data shows that all β-diketonate ligands are co-ordinated to the metal centre through both oxygens; however, in complexes of the type [ZrCl2L2] and [ZrCIL3]
已经制备了五个含有3-氰基戊烷-2,4-二酸酯和2-氰基-1-苯基丁烷-1,3-二酸酯配体(L)的锆配合物:[ZrCl 2(C 6 H 6 NO 2)2 ], [使用ZrCl 2(C 11 H ^ 8 NO 2)2 ],[使用ZrCl(C 6 H ^ 6 NO 2)3 ],[Zr的(C 6 H ^ 6 NO 2)4 ]和[Zr的(η-C 5 H ^ 5)(C 6 H 6 NO 2)3]。红外数据表明,所有的β-二酮酸酯配体都通过两个氧与金属中心配位。然而,在[ZrCl 2 L 2 ]和[ZrCIL 3 ]类型的络合物中,氰基也似乎是配位的。
