合成了N -(1 -甲基-4, 5- 二溴-2 -三氯乙酰基)甘氨酸甲酯(C9H10Br2N2O3, Mr=354. 01),X 射线单晶衍射确定其属于正交晶系,P2(1)2(1)2(1)空间群, a=6. 4237(18) , b=13. 445(4) , c=14. 054(4) , α=β=γ= 90°, V=1213. 8(6) 3, Z=4, Dc=1. 937Mg·m3, μ=6. 672mm-1, F(000) =688。有2257个可观察点[I>2σ(I)],最终R1 =0.0275, wR2 =0. 0682。X 射线晶体结构的分析表明该化合物含羰基、酰胺基、酯基与溴原子,并且通过N(2)H与O(2)分子间氢键连成一维链状结构。
Synthesis of N - (1 - methyl - 4, 5 - dibromo - 2 - trichloroacetyl) glycine methyl ester (C9H10Br2N2O3, Mr = 354. 01), X - ray diffraction determined that it belongs to the orthorhombic system, (4), α = β = γ = 90 ° (2) Space group a = 6.24237 (18), b = 13.445 , V = 1213.8 (6) 3, Z = 4, Dc = 1. 937 Mg · m3, μ = 6. 672 mm-1, F (000) = 688. There are 2257 observable points [I> 2σ (I)], the final R1 = 0.0275, wR2 = 0.0682. The analysis of the X-ray crystal structure shows that the compound contains a carbonyl group, an amide group, an ester group and a bromine atom, and forms a one-dimensional chain structure by hydrogen bonding between the N (2) H and O (2) molecules.
