利用柔性配体合成了配合物[Mn(pda)(bpp)](1)(H2pda=1,3-phenylenediacetic acid,bpp=1,3-bi(4-pyridyl)propane),并对其进行了元素分析、红外光谱和X射线单晶衍射测定。配合物1属于正交晶系,空间群为Pnna,a=1.965 2(6)nm,b=1.103 3(4)nm,c=0.963 9(3)nm,α=β=γ=90.0°,V=2.089 8(12)nm3,Z=4,Dc=1.416 Mg.m-3,μ=0.664 mm-1,F(000)=924,R1=0.040 2,wR2=0.133 2(I>2σ(I))。配合物1的结构单元由1个MnⅡ、1个1,3-pda和1个bpp构成。bpp交替连接MnⅡ形成1D右手螺旋链,进一步通过1,3-pda的连接构成2D螺旋层。从c轴方向看,发现1DZ字链构成2D(4,4)网格结构。同时还研究了配合物的热稳定性和电化学性质。
The complex [Mn (pda) (bpp)] (1) (H2pda = 1,3-phenylenediacetic acid, bpp = 1,3-bi (4-pyridyl) propane) Elemental Analysis, Infrared Spectroscopy and X-Ray Single Crystal Diffraction. The complex 1 belongs to the orthorhombic system with space group Pnna, a = 1.965 2 (6) nm, b = 1.103 3 (4) nm, c = 0.963 9 V = 2.089 8 (12) nm3, Z = 4, Dc = 1.416 Mg.m-3, μ = 0.664 mm -1, F 000 = 924, R1 = 0.040 2, wR2 = 0.133 2 (I> 2σ I)). The structural unit of complex 1 consists of one Mn II, one 1,3-pda and one bpp. bpp alternately connects Mn II to form a 1D right-handed helical chain, further forming a 2D helical layer through the connection of 1,3-pda. From the c-axis direction, the 1DZ word chain was found to form a 2D (4,4) grid structure. The thermal stability and electrochemical properties of the complexes were also studied.
