Cr(CNR)_3Cl_3和Cr(CNR)_3Cl_2B(C_8H_5)_4·H_2O(R=CH_2C_8H_5)的合成和性质研究

Studies on the Synthesis and Property of Cr(CNCH_2C_6H_5)_3Cl_3 and Cr(CNCH_2C.H_5),Cl_2B(C_6H_5)_4 H_2O

长期以来人们对羰基配合物进行了较为充分的研究,但忽略了与之对应的异腈配合物领域。本文在四氢呋喃溶剂中制得两个过渡金属异腈配合物,初步研究了它们的性质,并讨论了它们的红外光谱和热重分析。 1 实验部分 1。1 试剂和仪器 CrCl_3(thf)_3按文献合成。CNCH_2C_6H_5和NaB(C_6H_5)

The title metal isocyanides were synthesized by the substitution reaction of Ugand. The reaction of CNCH2C6H5 with CrCl3(thf)3 yielded Cr(CNCH2C6H5)3Cl3. B(C6H5)r anion was introduced into the reaction mixture only to form Cr(CNCH2C6H5)3Cl2B(C8H5)4. Two new compounds are all stable in air and unstable in chloroform, dichloromethane, acetone and other organic solvents. Their IR spectra and thermal stability have been investigated.
