In the present paper three reference systems: Percus-Yevick hard sphere (PYHS), one component plasma (OCP) and charged hard sphere (CHS) are employed to investigate the temperature-dependent structural properties of some simple liquid metals. The structure factor S(q), pair-distribution function g (r) and interatomic distance r1 of nearest neighbour atoms for Mg, Zn, Al, In, Tl and Pb are reported. Our own model potential is employed along with the local field correction due to Sarkar et al. (SS) to describe electron-ion interaction. It is seen that the CHS method alongwith the present form of model potential can explain more accurately the structural behaviour than PYHS and OCP methods.Za istraživanje temperaturno-ovisnih svojstava strukture nekih jednostavnih tekućih metala, primijenili smo tri referentna sustava: Percus–Yevickov tvrde kugle, jednokomponentne plazme i nabijenih kuglica. Izvješćujemo o strukturnom faktoru S(q), funkciji raspodjele parova g(r) i o međuatomskim razmacima r1 najbližih atoma u Mg, Zn, Al, In, Tl i Pb. Rabimo naš vlastiti modelski potencijal i popravku lokalnog polja prema Sarkaru i sur. za opis međudjelovanja elektron-ion. Nalazimo da metoda nabijene tvrde kuglice s primijenjenim modelskim potencijalom točnije opisuje strukturna svojstva nego druge dvije metode
