In this alluaudite structure, Co and Na atoms are located at the same general site with occupancies of 0.503 (5) and 0.497 (6), respectively. The other three Na and one of the two Mo atoms lie on special positions . The structure is compared with similar structures and other members of alluaudite family.The title compound, tetrasodium cobalt(II) tris[molybdate(IV)], was prepared by solid-state reactions.

In the packed structure, columns of complex moieties are stacked such that the neighboring units are oriented at 180° and laterally displaced with respect to each other. This prevents any overlap of the phenanthroline rings and thus there is no possibility of any π–π interactions between aromatic rings.In the title complex, [PtCl DOI: 10.1107/S160053681303256X/mw2118Isup2.hklStructure factors: contains datablock(s) I.

The asymmetric unit contains one cation and one tetrahedral anion, both in general positions. Based on comparison of the four carbonyl C—O bond lengths and C—Co—C angles, the anion is unperturbed by the cation, which is normal for an alkali metal fully encased by a cryptand cage.The title salt, [K(C DOI: 10.1107/S1600536814006758/nk2222Isup2.hklStructure factors: contains datablock(s) I.
