以二水合氯化铜,2,9-二甲基菲咯啉(dmphen)和硫氰酸铵为原料,通过沉淀反应和N,N-二甲基甲酰胺(DMF)重结晶得到了2个新型配合物[Cu(Ⅰ)(dmphen)(SCN)]n(1)和[Cu(Ⅱ)(dmphen)(DMF)(NCS)2](2),并采用元素分析、红外光谱、紫外可见光谱、X射线单晶衍射、热重分析及荧光光谱对其进行了表征。结果表明:1属单斜晶系,P21/n空间群,晶胞参数为a=1.211 1(4)nm,b=0.826 2(2)nm,c=1.367 5(4)nm,β=96.502(5)°,V=1.359 5(7)nm3,Z=4;该配合物通过硫氰酸根的桥联作用形成了一维Z链结构。2为三斜晶系,P1空间群,晶胞参数a=0.943 6(2)nm,b=1.010 9(2)nm,c=1.219 0(3)nm,α=95.628(4)°,β=103.114(4)°,γ=107.087(4)°,V=1.065 4(4)nm3,Z=2;2通过C-H…S氢键和π-π堆积构筑成一个超分子网络结构。热重和荧光分析表明:1比2具有更高的热稳定性,且1在603 nm处有最强荧光发射强度。
Two cupric chloride dihydrate, 2,9-dimethyl phenanthroline (dmphen) and ammonium thiocyanate were used as raw materials to get 2 by precipitation reaction and recrystallization from N, N-dimethylformamide (DMF) The new complexes [Cu (Ⅰ) (dmphen) (SCN)] n (1) and [Cu (Ⅱ) dmphen (DMF) (NCS) 2] were synthesized and characterized by elemental analysis, It was characterized by X-ray single crystal diffraction, TGA and fluorescence spectra. The results show that: 1 belongs to the monoclinic space group P21 / n with cell parameters of a = 1.211 1 (4) nm, b = 0.826 2 (2) nm, c = 1.367 5 (5) °, V = 1.359 5 (7) nm3, Z = 4. The complex formed a one-dimensional Z-chain structure by thiocyanate bridging. 2 is a triclinic system with P1 space group. The unit cell parameters are a = 0.943 6 (2) nm, b = 1.010 9 (2) nm, c = 1.219 0 = 103.114 (4) °, γ = 107.087 (4) °, V = 1.065 4 (4) nm3, Z = 2; 2, a supramolecular network structure is formed by CH ... S hydrogen bonding and π-π stacking. Thermogravimetry and fluorescence analysis showed that 1 has a higher thermal stability than 2 and 1 has the strongest fluorescence emission intensity at 603 nm.
