Refinement details


Refinement remarks: Commensurate structure refined within the superspace formalism. Modulation of CoCl4 and N(CH3)4 groups refined using rigid body restrictions. WARNING: This CIF has been standardized with the program JANA2006 from the published data. An alternative description in terms of translation and rotations of rigid groups is given within this CIF in the datablock TMATC-Co_MOD_RG [ Help ]
