The crystal structures of benzoate compounds were determined by X-ray diffraction analyses. The monomeric benzoate form ?$Cu(O_2CC_6H_5)_2(2apy)_2$?(2apy=2-aminopyridine) is composed of trans oriented ligands around central copper(II) atom, where benzoates acts as asymmetrical chelates (Cu-O 1.97 and 2.65 L). On the other hand, dimeric form ?$Cu_2(O_2CC_6H_5)_4(apy)_2$? reveals paddle - wheel type structure where 2-aminopyridine acts as axial ligand via pyridine nitrogen atom. All compounds were characterized by standard physico-chemical methods and tested for their fungal mycelial growth retardation activity for wood fungi Tremetes versicolor and Antrodia vaillantiiSintetizirani sta bili dve enojedrni in dve koordinacijski spojini bakrovega bnezoata in acetata z 2-aminopiridinom. Z rentgensko difrakcijsko analizo je bila določena kristalna struktura obeh benzoatnih spojin. V enojedrni benzoatni obliki ?$Cu(O_2CC_6H_5)_2(2apy)_2(2apy)=2-aminopiridin$?) so koordinirani ligandi v trans položaju okoli osrednjega bakrovega(II) atoma, kjer so benzoati asimetrični kelati (Cu-O 1.97 in 2.65 L). Po drugi strani dvojedrno obliko ?$Cu_2(O_2CC_6H_5)_4(2apy)_2$? predstavlja strukturni tip mlinskega kolesa z 2-aminopiridinom, ki se veže aksialno preko piridinskega dušikovega atoma. Vse spojine so bile karakterizirane s standardnimi fizikalno-kemijskimi metodami in testirane za njihovo zaviralno aktivnost pri rasti micelija lesnih gliv pisane ploskocevke in bele hišne gobeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaSlovensko kemijsko društvo
