Abstract
Abstract: New Ca3Ga2Ge4O14-type crystals, La3(M1/3Ga2/3)Ga5O14d (M=Mo6+ and W6+; LMG and LWG) were synthesized by the solid state reaction and grown using the micro-pulling down (μ-PD) method. The μ-PD growth of these two compounds showed that the crystals melt incongruently. The structure of these crystals has been refined using single-crystal X-ray diffraction data. Mo and W atoms were found to be ordered in the octahedral site coordinated by six oxygen atoms.
