Abstract: The title compound, [BaPt(CN)₄(C₁₂H₂₄O₆)(H₂O)₂], contains a polymeric chain of alternating complexes of Ba²⁺ and Pt²⁺. A ten-coordinate Ba²⁺ complex results from coordination of the metal by 18-crown-6 and two water molecules, and N-atom coordination by a cyano group of [Pt(CN)₄]^2- and by a second cis-related cyano group of a second [Pt(CN)₄]^2- generated by a crystallographic b-glide. Crosslinking via hydrogen bonds involving the remaining two cyano N atoms completes the crystal structure in the a and c directions.
