Higher Dimensionality in the Mg-Co-B System: Synthesis and Structure of Incommensurate Composite Mg_1+εCo₄B₄.

ABSTRACT: Guided by high-temperature in situ X-ray diffraction, the discovery and synthesis of Mg_1+εCo₄B₄ (ε ≈ 0.272) using a MgH₂ hydride precursor is reported, along with a detailed crystal structure description and measurement of magnetic properties. The mismatch in lattice periodicities between Mg and Co-B substructures places Mg_1+εCo₄B₄ in the family of incommensurate composite crystals and prompted structural refinement in a (3 + 1)-dimensional model. The structure of Mg_1+εCo₄B₄ (P4₂/ncm(00γ)s00s, a = 6.75847(7) Å, c = 3.94007(8) Å, q = (0, 0, 1.2721(3))) was refined from neutron powder diffraction and high-resolution powder X
