The title polymeric complex, [PbPd(NCS)₄(C₂₀H₃₆O₆)(H₂O)]_n or {[Pb(DC18C6-A)(H₂O)][Pd(SCN)₄]}_n (DC18C6-A = cis-syn-cis-dicyclo­hexyl-18-crown-6), has been synthesized by the reaction of dicyclo­hexyl-18-crown-6 with PdCl₂ and Pb(SCN)₂. The SCN groups bridge [Pb(DC18C6-A)(H₂O)]²⁺ complex cations and [Pd(SCN)₄]²⁻ complex anions to form infinite polymeric chains.
