  • Analysis of the crystal packing and coordination geometry.

    • Main Results:

    • The crystal structure of K2Cr4O13 was solved in the monoclinic Pc space group.
    • The structure features discrete [Cr4O13]2- zigzag chains.
    • These chains are interconnected by charge-balancing potassium (K+) cations.
    • The tetrachromate anion exhibits a specific conformation distinct from those in related compounds.

    Conclusions:

    • The structural characterization of K2Cr4O13 provides new insights into chromium oxide chemistry.
    • The observed zigzag chain motif represents a novel structural category for tetrachromate anions.
    • Further investigation into the conformational variations of tetrachromate anions is warranted.
