用L，L′ =（a）脂族和环醚（包括多官能配体）（B）烷基氰化物，（c）芳族叔胺或（d）a和c的混合物制备了新的，通常具有高氧敏性的（“半”基）Cl-Cr-N（SiMe 3）2（L）n，I和Cr[N（SiMe 3）2]2LL′，II.通过元素分析和化学反应对产物进行了表征。化学和物理性质强烈地依赖于L、L′的性质，通过改变配位体的配位方式，可以调节Cr ~（3+）N键的氧敏性、热稳定性、溶解性和与表面反应的活性。建立了各种LL′组合的经验反应性系列和配体不稳定性相互关系。铬（II）的醇盐合成，开环聚合，并在热解反应中的一些配合物的行为进行了讨论。
Novel, generally highly oxygen sensitive („hemi”︁) ClCrN(SiMe3)2(L)n,I, and Cr[N(SiMe3)2]2LL′,II, were prepared with L, L′ = (a) aliphatic and cyclic ethers (including polyfunctional ligands) (b) alkyl cyanides, (c) aromatic tertiary amines or (d) mixtures of a and c. The products are characterized by elemental analysis and chemical reactions. Representative reflectance spectra are presented.Chemical and physical properties are strongly dependent on the nature of L, L′ and oxygen sensitivity, thermal stability, solubility and reactivity of the CrN linkage (in reactions with surface ) could be regulated by varying the coordinated ligands. Empirical reactivity series for various LL′ combinations and ligand lability interrelationships were established. Behavior of some complexes in Cr(II) alkoxide synthesis, ring opening polymerizations, and in pyrolysis reactions is discussed.
