Abstract

Kompleks tembaga(II) dengan 2-feniletilamin telah disintesis melalui reaksi antara logam CuCl₂·2H₂O dan ligan 2-feniletilamin dengan perbandingan mol logam dan mol ligan 1:2 dalam metanol. Senyawa kompleks yang dihasilkan berupa kristal berwarna oranye dengan prediksi rumus molekul [Cu(II)-(2-feniletilamin)₂(H₂O)₂]Cl₂·2H₂O. Rumus ini diperoleh dari hasil penentuan kadar Cu = 14,04%, C = 41,36%, H = 6,60% dan N = 6,06%. Spektra inframerah menunjukkan serapan khas ikatan logam dengan ligan yaitu vibrasi Cu-N muncul pada serapan 347,19 cm⁻¹ dan vibrasi Cu-O pada serapan 300,90 cm⁻¹. Analisis DTA/TGA menunjukkan bahwa kompleks mengandung dua molekul air hidrat. Senyawa kompleks bersifat paramagnetik dengan nilai Peff sebesar 1,97 BM. Suseptibilitas magnetik senyawa kompleks memiliki interaksi feromagnetik, dengan konstanta Weiss, θ, +9,72 dan terjadi pada suhu Curie, Tc, 15 K.

Complex copper(II) with 2-phenylethylamine was synthesized from reaction between CuCl₂·2H₂O and 2-feniletilamin with ratio mole of metal and ligand 1:2 in methanol. Crystalline solid coloured orange is predicted molecular formula [Cu(II)-(2-feniletilamin)₂(H₂O)₂]Cl₂·2H₂O. This formula is constructed from the determination of content Cu = 14,04%, C = 41,36%, H = 6,60% dan N = 6,06%. IR absorption spectra showed the typical vibrations of metal with ligand is occured vibration of Cu-N on the wavenumber 347,19 cm⁻¹ and Cu-O on the wavenumber 300,90 cm⁻¹. DTA/TGA analysis showed that complex has two molecules of hydrat. This complex has paramagnetic with Peff value 1,97 BM. Magnetic susceptibility of this complex has feromagnetic interaction with Weiss constant, θ, +9,72 and Temperature Curie constant, Tc at 15 K.
