The aim of this paper is to study and investigate the ii-open sets in topological spaces and to obtain a relationship among b-open, pre-open, semi-open, -open and -open sets. Some new types of separation axioms such as ii-T0, ii-T1, ii-T2, ii-R0 and ii-R1 axioms in topological spaces by using ii-open sets also are introduced. The relationships among ii-T0, ii-T1, ii-T2 and some other separation axioms are investigated.
