摘要

Single crystals of Ca_(15)(CBN)_6(C_2) _2F_2 were obtained by the reaction of graphite, hexagonal BN and CaF_2 with an excess of distilled Ca metal in silica-jacketed Ta ampoules at 1300 K. The title compound is transparent red and crystallizes isopointal to Ca_(15)(CBN)_6(C_2)_2O adopting the cubic space group Ia3?d (no. 230, Z = 8) with the cell parameter a = 1653.6(4) pm. Its vibrational spectra are compared with IR and Raman data of similar compounds from the literature and with the newly measured Raman spectra of Ca_5(BC_2)(C_2)Cl_3 and Ca_9(BC_2)_2Cl_8.
