Abstract

Abstract: Awine 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(I_O)) were used for structure refinement. The final deviation factor R=R_w=0.094. The complex crystallizes in triclinic with space group P1. The unit cell parameters are as follows:a=10.301(4)Å.b=12.038(7)Å,c=13.806 (5)Å;α=88. 370(48), β=69.616 (27), γ=81.700(46); V=1587.6( 1.31)Å³, Z=2, d_calc= 1.44 g/cm⁵, d_exp=1.46g/cm³.

Key words: Cobalt, HPMTFP, Ethanol, Mixed ligand complex, Crystal and molecular structure
