摘要
合成了芳香基硼氨配合物MesNHBMes_2及其As的衍生物AsCl_2NMesBMes_2(Mes=Me_3C_6H_2-),并通过X线衍射进行了结构测定。结果表明,带有配体的N-B中心呈平面形,平面间扭曲的角度一般小于10°,B-N原子之间多重键的性质无改变。用M_0K_a(λ=0.0071069nm)在130K低温下X线衍射所得的晶体数据为:1.MesNHBMes_2,C_(27)H_(34)BN,a=0.8200(1)nm,b=1.0370(3)nm,C=1.5134(3)nm,α=109.38(2)°,β=80.96(2)°,γ=108.71(2)°,三斜晶体,空间群p(?),R=0.063。2.AsCl_2NMesBMes_2,C_(27)H_(33)AsBCl_2N,a=2.2681(3)nm,b=8.3510(9)nm,C=2.7961(3)nm,β=98.80(1)°,单斜晶体,空间群P2_(1/a)。
This article described the synthesis and X-ray structural characte-rization of the aminoborane HNMesBMes_2 and its derivative AsCl_2 NMesBMes_2.The structures reveal that the twist angles between these planes are small.The multiple chatacter of the B-N bond remains essentially unchanged in the two compounds.Crystal data Mo Ka(λ=0.071069nm)at 130 K are as follows:1.HNMesBMes_2,C_(27)H_(34)BN,a=0.8200(1)nm,b=0.10370(3)nm,c=1.5134(3)nm,α=109.38(2)°,β=80.96(2)°,γ=108.71(2)°,z=2,triclinic,space group pl,R=0.063.2.AsCl_2NMesBMes_2,C_(27)H_(33)AsBCl_2N,a=2.2681(3)nm,b=0.83510(9)nm,c=2.7961(3)nm,β=98.80(1)°,monoclinic,space group p2_1/a。
