在水-吡啶混合体系中,以5-羟基-1,3-苯二甲酸(简作HO-H2BDC )、1,2-二(4-吡啶)乙烷(简作bpe)为配体与Co(NO3)2·6H2O反应,培养出[Co2(HO-BDC)2(bpe)2( H2O)2]n·n(py)·nH2O(py =pyridine)的紫色单晶,该晶体属三斜晶系,P1空间群,晶胞参数a=1·0245(3) nm,b=1·1467(3) nm,c=1·2430(4)nm,α=68·915(5)°,β=67·163(4)°,γ=71·373(4)°,V=1·2279(6) nm3,Z=1,Mr=979·70,Dc=1·325Mg/m3,F(000)=506,μ=0·740 mm-1,R1=0·0515,wR2=0·1058.该配位聚合物中在ac平面上具有规则平行四边形纳米尺寸的孔,其孔径大小约为1·025 nm×1·354 nm,而且通过氢键相互作用连成具有双层结构的2D网络结构. TGA曲线表明,配位聚合物的失重发生在110 ～150℃之间,总失重约为80·1%,最终产物为Co2O3.
In the water-pyridine mixed system, 5-hydroxy-1,3-benzenedicarboxylic acid (abbreviated as HO-H2BDC) and 1,2-bis (4-pyridyl) ethane (NO3) 2 · 6H2O to form a purple single crystal of [Co2 (HO-BDC) 2 (bpe) 2 (H2O) 2] n · n (py) · nH2O (py = pyridine) (3) nm, b = 1.1467 (3) nm, c = 1.2430 (4) nm, α = 68.915 (5) °, β = 67 · 163 (4) °, γ = 71 · 373 (4) °, V = 1.2279 (6) nm3, Z = 1, Mr = 979 · 70, Dc = 1 · 325 Mg / 000) = 506, μ = 0 · 740 mm-1, R1 = 0 · 0515, wR2 = 0 · 1058. The coordination polymer has pores with a regular parallelogram nanometer size in the ac plane, and the pore size is about 1 · 025 nm × 1 · 354 nm, and the 2D network structure was double-layered by hydrogen bonding interaction.The TGA curve showed that the weight loss of the coordination polymer occurred between 110-150 ℃ and the total weight loss was about 80.1%, the final product is Co2O3.
