摘要
以1-苯基-3-甲基-4-三氟乙酰基-吡唑啉酮-5(简称HPMTFP)和乙醇为配体合成了具有Co(PMTFP)_2·2C_2H_5OH分子式的钴配合物。对配合物的溶解性、摩尔电导、磁性、热谱、中红外光谱、远红外光谱进行了研究。用四圆单晶衍射仪测定了该配合物的分子及晶体结构。晶体属三斜晶系。P1空间群,晶体学参数:a=10.301(4),b=12.038(7),c=13.806(5);α=88.37(5),β=69.62(3),γ=81.70(5)~9;V=1587.6(1.3)3,z=2,d_(calc)=1.44g/cm^3,d_(exp)=1.46g/cm^3。
A wine red mixed ligand complex of 1-phenyl-3-methyl-4-trifluoro-acetyl pyrazolone-5(HPMTFP)and ethyl alcohol with cobalt having molecular formula Co(PMTFP)2.2C2H5OH has been synthesized and studied by solubility, conductometric method, magnectometry, IR, far-IR, thermo analysis(TG-DTA) as well as single crystal X-ray diffractometry. Its crystal and molecular structure has been determined by a single crystal X-ray diffractometer. 4576 independent reflections were collected, of which 2698 observable reflections (I≥2σ(IO)) were used for structure refinement. The final deviation factor R = Rw = 0.094. The complex crystallizes in triclinic with space group Pl. The unit cell parameters are as follows:a = 10.301(4) A.b = 12.038(7) A,c = 13.806 (5) A ;α=88. 370(48), β=69.616 (27), γ=81.700(46 ); V = 1587.6( 1.31) A 3, Z=2, dcalc= 1.44 g/cm5, dexp = 1.46g/cm3.
