在水中,以2-羰基丙酸水杨酰腙与硫酸铜反应,制得新配合物Cu(C10H8N2O4)(H2O)2(C10H8N2O42-为2-羰基丙酸水杨酰腙负离子),并以水为溶剂培养了单晶,测试了晶体结构,该单晶为深绿色,属单斜晶系,空间群为C2/c,晶胞参数a=1.1297(1)nm,b=0.9824(8)nm,c=2.1973(3)nm,β=91.91(8)°,V=2.43749(8)nm3,Z=8,μ=1.817mm-1,Dc=1.743Mg·m-3,F(000)=1304,R=0.0264,wR=0.0654,GOF=1.052。其测试结果表明在配合物中Cu2+处于五配位的四方锥配位环境,配位原子分别来自1个三齿配体2-羰基丙酸水杨酰腙负二价离子的2个O原子和1个N原子,2个水分子中的O原子,其中1个水分子的O原子处于四方锥的锥顶,锥底的配位原子基本处于同一平面上。对该配合物所作的皿内抑菌试验和盆栽活体实验表明,配合物对小麦条锈病、白菜黑斑病及辣椒疫霉菌等分别有96%、89%、100%的抑制率,且有一定的助长作用。
The new complex Cu (C10H8N2O4) (H2O) 2 (C10H8N2O42- is 2-carbonyl propionic acid salicyloyl hydrazone anion) was prepared by the reaction of 2-oxopropionate salicyloyl hydrazone and copper sulfate in water, and the water was used as the solvent The crystal structure of this single crystal is dark green and belongs to the monoclinic system with space group C2 / c. The unit cell parameters a = 1.1297 (1) nm, b = 0.9824 (8) nm and c = 2.1973 (3) nm, β = 91.91 (8) °, V = 2.43749 (8) nm3, Z = 8, μ = 1.817mm-1, Dc = 1.743Mg · m-3, F (000) = 1304, R = 0.0264, wR = 0.0654, GOF = 1.052. The test results show that Cu2 + is in a five-coordinate tetragonuclear coordination environment in the complex, and the coordination atoms come from two ortho-divalent O-atoms of one tridentate ligand 2-carbonylpropionate salicyloylhydrazone and one N atoms, O atoms in two water molecules, of which one O atom of water molecules in the pyramid top of the pyramid, the conical bottom cone atoms are basically in the same plane. The antibacterial activity test and in vivo pot experiment showed that the complex had 96%, 89% and 100% inhibitory rate against wheat stripe rust, cabbage black spot disease and Phytophthora capsici respectively, The role of encouragement.
