ABSTRAK

senyawa kompleks SengII dengan asam piridin-26-diarboksilat telah disintesis dengan dua metode berbeda. metode pertama di lakukan dengan metode refluks mereaksikan larutan logam dan ligan dengan perbandingan mol tertentu dalam pelarut methanol air 11. metode kedua di rekasikan larutan logam dan ligan dengan perbandingan mol 12 pelarut yang digunakan sama dengan metode pertama. kristal jernih berbentuk persegi dengan formula molekul lznHlipttdipi.26ll0vroJcl.5HO dihasilkan dari sintesis dengan metode pertama. kristal seperti jarum dengan formula molekul lz.H4lptczzEpJor2Hro dihasilkan dari sintesis dengan metode kedua. kedua senyawa kompleks yang di hasilkan di uji toksisitasnya dengan metode Brine Shrimp Lethality Test BSLT nilai Lc50 untuk masing-masing senyawa berturut-turut adalah 989.26 dan 503.32 ppm.


ABSTRACT

complexes of zinc II with pyridine -26 dicarboxylic acid were synthesized from a recation between zinc II chloride and pyridine -26 dicarboxylic acid with two different methods. the first method was carried out by reflux method mixing a certain mole ratio of metal and ligand in the mixed solution of methanol water 11 as the solvent. the second method was carried out by employing a direct reaction of metal and ligand in a 12 mole ratio of the same solvent as it is of the first method. the first method yielded a small clear crystal grains shaped like parallelogram with the molecular formula of lznHii..ripbz6dt0uOlct.5flo complex I-trinuclear. the second method yielded the colorless needle like crystals and molecular formula lznEyipiciHplcl..2Hro complex II-dinuclear. both complex compounds were tested their toxicity using brine shrimp lethality test BSLT method and obtained LC50 values of 989.26 and 503.32 ppm respectively
