The equilibrium geometries and bounding properties of the open shell elemental cluster BCHe^2^+ in ground state have been studied using ab initio-methods. Calculations were performed using the 6-31G^*, 6-311G^*^*, 6-311+G^*^*, 6-311++G^*^*, 6-311G^*^*(2df), 6-311G^*^*(3df,2p) basis sets with unrestricted Hartree Fock and Moller Plesset perturbation theory to fourth order (UMP4). The results predict that there are weak bonds between He and BC group in the three geometries. The difference in energy for the three geometries are very small and so the cluster will penerally be nonrigid.
