Abstract

Senyawa kompleks binuklir kobalt(II) dengan ligan (6E)- N2-((E)-2-(6-aminopiridin-2-ilimino)-1,2-difeniletilidin)piridin- 2,6-diamina telah berhasil disintesis menggunakan metode refluks. Kristal yang diperoleh berwarna oranye dan berbentuk jarum kecil. Senyawa kompleks tersebut dapat menyerap warna pada panjang gelombang maksimum 460 nm. Hasil analisis menggunakan elemental analyzer dan AAS menunjukkan bahwa kompleks yang terbentuk memiliki rumus molekul [Co2((6E)-N2- ((E)-2-(6-aminopiridin-2-ilimino)-1,2-difeniletilidin)piridin-2,6- diamina)2(CH3COO)4]∙H2O. Rumus molekul juga didukung dengan data TGA yang menunjukkan dekomposisi air kristal pada suhu 105-120 °C. Spektrum FTIR menunjukkan puncak khas vibrasi C=N dan Co-N masing-masing pada bilangan gelombang 1658,84 cm-1 dan 418,57 cm-1. Uji toksisitas senyawa ini dilakukan dengan metode Brine Shrimp Lethality Test (BSLT) dan dihasilkan nilai toksisitas LC50 sebesar 151,35 mg/L. ======================================================================================================================== Binuclear cobalt(II) complex with (6E)-N2-((E)-2-(6- aminopyridin-2-ylimino)-1,2-diphenylethylidine)pyridin-2,6- diamine ligand has been synthesized using reflux method. The orange crystal produced and had needle shaped. The max wavelenght absorbed is 460 nm. Data analysis from elemental analyzer and AAS results show that molecular formula of complexes is [Co2((6E)-N2-((E)-2-(6-aminopiridin-2-ilimino)- 1,2-difeniletilidin)piridin-2,6-diamina)2(CH3COO)4]∙H2O. This molecular formula was supported by TGA analysis that show decomposition of crystal water molecul at 105-120 °C. The FTIR spectrum showed characteristic vibrations of C=N and Co-N at υ = 1658,84 cm-1 and 418,57 cm-1, respectively. Toxicity test was observed by Brine Shrimp Lethality Test (BSLT) method and the LC50 value is 151,35 mg/L.
