Mg Mo
MgMo crystallizes in the triclinic P1 space group. Mg(1) is bonded in a 12-coordinate geometry to six equivalent Mg(1) and six equivalent Mo(1) atoms. All Mg(1)-Mg(1) bond lengths are 2.85 Å. There are a spread of Mg(1)-Mo(1) bond distances ranging from 2.65-3.37 Å. Mo(1) is bonded in a 12-coordinate geometry to six equivalent Mg(1) and six equivalent Mo(1) atoms. All Mo(1)-Mo(1) bond lengths are 2.85 Å.
