GaMgMo4O7 and Fe2Mo4O7 - Two low-valent molybdenum oxides with a fully ordered Sc0.75Zn1.25Mo4O7 type structure

Research output: Contribution to journalArticlepeer-review

Abstract

GaMgMo4O7 and Fe2Mo4O7 were prepd. by sintering at 1200. Their crystal structures were detd. from single crystal diffractometer data: space group Imma, with a 6.016(3), b 5.712(1), c 16.606(4) A (GaMgMo4O7) and a 6.018(1), b 5.782(1), c 16.901(5) A (Fe2Mo4O7), Z = 4. The structure is interpreted as a substitutional deriv. of a cubic closed-packing of O ions with the Mo cluster atoms occupying octahedral holes. While Ga is in tetrahedral and Mg in octahedral O coordination, bond valences suggest that Fe(II) is in the tetrahedral and Fe(III) in the octahedral sites.
