Preparation and Analysis of Neutral Complexes of Cooper(ll) with Chromone-2,3-Carboxylic Acides

Abstract

Kompleksni spojevi su spojevi koji sadrže centralni atom metala okruženog određenim brojem iona ili skupina, koje se nazivaju ligandi. Cilj ovoga rada bio je sintetizirati spoj s potencijalnim antikancerogenim svojstvima i/ili drugim terapeutskim svojstvima. Kao ligandi korišteni su derivati benzopirona, a kao izvor centralnog metala bakra(II) poslužile su soli tog metala (acetat, sulfat, nitrat i klorid). Kompleksi su pripravljeni te identificirani elementnom analizom kako bi im se odredila empirijska formula. Nakon provedenih analiza utvrđeno je da vjerojatna kemijska formula odgovara formuli $\left [ CuL_{2}\cdot 2H_{2}O \right ]$ .Complexes are compounds which consists of the central metal atom surrounded by a number of ions or groups, called ligands. The aim of this work was synthesis of the compounds with potential anticancer and/or other therapeutic properties. Benzopyrone derivatives were used as ligands, and copper(II) salts (acetate, sulfate, nitrate, and chloride) as the source of the metal copper(II). The complexes were prepared and identified by elemental analysis in order to determine the empirical formula. After analysis it was revealed that chemical formula of the newly synthesized compound is $\left [ CuL_{2}\cdot 2H_{2}O \right ]$
