报道了化合物四乙基溴化铵(C2H5)4N.Br(1)和四乙基溴化铵硫脲(C2H5)4N.Br.4/3tu(2)的多组分结构,并对其进行了单晶X-射线衍射的表征。其中化合物1的晶体为三方晶系,R-3c空间群,晶胞参数:a=12.1116(1),c=35.5332(6),V=4514.06(9)3,Z=18;化合物2的晶体为三斜晶系,P-1空间群,晶胞参数:a=10.0446(1),b=14.8420(2),c=17.7756(3),α=103.953(1)°,β=105.934(1)°,γ=108.474(1)°,V=2320.41(6)3,Z=2。在化合物1的晶体结构中,有序的阳离子(C2H5)4N+和阴离子Br-对之间没有氢键作用,而在化合物2的晶体结构中,(C2H5)4N+阳离子位于ac平面内折叠的硫脲-溴层之间,其中每一个硫脲都与溴原子形成交联的平面链状结构。
The multicomponent structure of the compounds tetraethylammonium bromide (C2H5) 4N.Br (1) and tetraethylammonium bromide thiourea (C2H5) 4N.Br.4 / 3tu (2) has been reported and carried out Characterization of single crystal X-ray diffraction. Among them, the crystal of compound 1 is a trigonal system. The R-3c space group has a unit cell parameter of a = 12.1116 (1) , c = 35.5332 (6) , V = 4514.06 2 crystals are triclinic with space group P-1 and unit cell parameters: a = 10.0446 (1) , b = 14.8420 2, c = 17.7756 3, α = 103.953 (1) ° , β = 105.934 (1) °, γ = 108.474 (1) °, V = 2320.41 (6) 3, Z = 2. In the crystal structure of compound 1, there was no hydrogen bond between the ordered cation (C2H5) 4N + and the anion Br-pair, whereas in the crystal structure of compound 2, the (C2H5) 4N + cation was located in the ac plane folded thiourea Between the bromine layers, a planar chain structure in which each thiourea forms a crosslink with a bromine atom.
