Na Ca Mn
NaCaMn is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaCaMn clusters. Na(1) is bonded in a single-bond geometry to one Mn(1) atom. The Na(1)-Mn(1) bond length is 0.18 Å. Ca(1) is bonded in a single-bond geometry to one Mn(1) atom. The Ca(1)-Mn(1) bond length is 0.09 Å. Mn(1) is bonded in a linear geometry to one Na(1) and one Ca(1) atom.
