一种新型β-二亚胺镍(Ⅱ)配合物的合成及其结构研究

SYNTHESIS AND STRUCTURE STUDIES OF DIKETINIMATONICKEL COMPLEXES

共轭的含氮配体，特别是其过渡金属配合物作为模拟生命体系中的一些现象而被人们广泛研究和重视［１］。我们在用二（三甲基硅基）甲基锂与两摩尔的不含α－Ｈ的腈进行加成反应时，由于三甲基硅基的１，３－迁移反应得到了一类非常有趣的五元共轭二亚胺配合物［２］。在本...

Two novel Diketinimatonickel complexes (L=HNC(Ph)CHC(Ph)NH)THZ](2) and (L=HNC(Ph)CHC(\+\{t\}Bu)NH) (4) were synthesised and the crystal structure of complexes ( 2 ) was determined by single crystal Xray structure analysis. The crystal data are as follows: NiC\-\{30\}H\-\{26\}N\-4\{2(C\-2H\-5OC\-2H\-5),\} FW=649.50, orthorhombic, space group Pbca, \%a\%=11.2243(14), \%b=17.236(2), c=18.429(2)\%, \%=90,=90, =90, V=33565.2(7)\%\+3, Z=4, \%Dc\%=1.210 gcm\+3, =\{5.81\} cm\+\{-1\}, \%F\%(000)=1384, \%T\%=294(2)K. 4542 unique reflections , R=0.0297, w\%R\%=\{0.0826.\}\=\;
