Abstract We describe the properties of low-lying states of ¹⁰²Ru within the framework of the proton-neutron interacting model IBM2. The theoretical predictions of the ground state, quasi-γ and quasi-β bands, and the ratios of the B(E2) transition strengths are reproduced very well. The structural properties of ¹⁰²Ru are identified in the parameters space of the interacting boson model (IBM2). The characteristic feature of the energy spectrum structure exhibits that ¹⁰²Ru is very close to the critical point of U_πν(5)–O_πν(6) transition and towards U_πν(5) symmetry. The key sensitive quantities of the B(E2) branching ratio clearly indicate that ¹⁰²Ru is a primary O_πν(6) symmetry, while with a somewhat U_πν(5) symmetry. It is possible that the shape coexistence persists in ¹⁰²Ru, whereas the evident fingerprint of the shape coexistence has not been observed.
