合成了新颖的配合物{[Zn_(1.5)(tttmb)(Hbptc)]·H_2O}_n,属于四方晶系,P4_32_12手性空间群,Flack常数0.000(11),晶胞参数:a=14.296(2)A,b=14.296(2)A,c=33.755(7)A,α=90.00,β=90.00,γ=90.00,V=6889.2A~3,Z=4,D_(calc)=1.607 g·cm~(-3),u=1.126 mm~(-1),F(000)=3424,R_1=0.0371,wR_2=0.0894.在其结构单元中,Zn原子与两个Hbptc~(3-)配体及两个tttmb配体配位,形成四配位的扭曲四面体,羧酸配体Hbptc~(3-)连接Zn原子形成小鸟状的二维结构,而tttmb沿c轴方向与Zn原子形成左手螺旋链并相互连接形成3D结构框架,最后,Zn~Ⅱ/Hbptc~(3-)嵌入到三维Zn~Ⅱ-tttmb框架中形成三维微孔的网络结构。
The novel complex {{Zn_ (1.5) (tttmb) (Hbptc)] · H_2O} _n belongs to the tetragonal system, the P4_32_12 chiral space group has a Flack constant of 0.00011 and the unit cell parameter is a = 14.296 Α = 90.00, β = 90.00, γ = 90.00, V = 6889.2A ~ 3, Z = 4, D calc = 1.607 g (2) A, c = 33.755 Cm ~ (-3), u = 1.126 mm -1, F (000) = 3424, R_1 = 0.0371, wR_2 = 0.0894. In its structural unit, Zn atom and two Hbptc ~ Ligand and two tttmb ligands to form a four-coordinated distorted tetrahedron. The carboxylic acid ligand Hbptc ~ (3-) connects Zn atoms to form a birdie-like two-dimensional structure, and tttmb along the c-axis with Zn Atoms form left-handed helical chains and are connected to each other to form a 3D structural framework. Finally, Zn ~ Ⅱ / Hbptc ~ (3-) is embedded into the three-dimensional Zn ~ Ⅱ -tttmb framework to form a three- dimensional micropore network structure.
