The strontium borogermanate Sr3–x/2B2–xGe4+xO14 (x = 0.32) was synthesized by high-temperature solid-state reaction of SrO, GeO2, and H3BO3 in a NaF/KF flux system using platinum crucibles. The structure determination revealed that Sr3–x/2B2–xGe4+xO14 (x = 0.32) crystallizes in the trigonal space group P321 (No. 150) with the parameters a = 800.7(2) and c = 488.8(2) pm, with R1 = 0.0281, wR2 = 0.0671 (all data), and Z = 1. The crystal structure of Sr3–x/2B2–xGe4+xO14 (x = 0.32) consists of distorted SrO8 cubes, GeO6 octahedra, GeO4 tetrahedra, and BO4 tetrahedra. In addition to the structural investigations, Raman and IR spectroscopic investigations were carried out.
