Abstract
We investigate quantum phase transitions in the three-dimensional orthogonal-dimer system of the compound by means of the series expansion technique. We then discuss the phase diagram where the dimer phase, the Haldane phase, the frustration-induced disordered phase and the magnetically ordered phase compete with each other. It is found that the compound is located in the dimer phase close to the phase boundary.
