We present a structural analysis of the substituted system(Ba$_{1-x}$Sr$_{x}$)CuSi$_{2}$O$_{6}$, which reveals a stable tetragonalcrystal structure down to 1.5 K. We explore the structural details withlowtemperature neutron and synchrotron powder diffraction, room-temperature andcryogenic highresolution NMR, as well as magnetic- and specific-heatmeasurements and verify that a structural phase transition into theorthorhombic structure which occurs in the parent compound BaCuSi2O6, is absentfor the x = 0.1 sample. Furthermore, synchrotron powder-diffraction patternsshow a reduction of the unit cell for x = 0.1 and magnetic measurements provethat the Cu-dimers are preserved, yet with a slightly reduced intradimercoupling Jintra. Pulse-field magnetization measurements reveal the emergence ofa field-induced ordered state, tantamount to Bose-Einsteincondensation (BEC) oftriplons, within the tetragonal crystal structure of $I\,4_{1}/acd$. Thismaterial offers the opportunity to study the critical properties of triploncondensation in a simple crystal structure.
