[Zn(NH3)3][Cu(CN)2]2 contains trigonally coordinated CuI atoms within helical -Cu-CN-Cu-CN- chains. The bridging CN groups are disordered. The third coordination site of Cu is occupied alternately by terminal CN ligands and -CN-Zn(NH3)3 groups.
(C4H12N2)3[Mo8O27] contains infinite chains of anionic octamolybdate clusters fused together by linear Mo-O-Mo bonds. The extra-chain piperazinium cations provide charge balance.
(C4H12N)2[H8Co2Mo6O32P4].5H2O crystallizes as a polymeric ionic complex. Anionic chains, consisting of [Mo6O12(OH)3(HxPO4)4]n− clusters, are held together by Co2+ ions to form an infinite one-dimensional structure.
