Inorganic molecular wires
There are a few different classes of inorganic molecular wires. Some, for example, consist of subunits related to Chevrel clusters. The synthesis of Mo6S9−xIx was performed in sealed and vacuumed quartz ampoule at 1343 K. In Mo6S9−xIx, the repeat units are Mo6S9−xIx clusters, which are joined together by flexible sulfur or iodine bridges. Chevrel-phase Co6Se8L'6 (L' = Ph2PN(H)R, Ph = phenyl, R = 4-tolyl; R = isopropyl) clusters have also been assembled into molecular wires by metalating edge-sites with zinc. The exposed zinc sites bind to ditopic organic linkers (4,4'-bipyridine and tetrapyrido[3,2-a:2′,3′-c:3″,2″-h:2‴,3‴-j] phenazine) and form nanowire structures.

In other examples, research has demonstrated that molecular wires can be comprised of metal ions that are bridged by halogens, denoted as "MII/MIV mixed-valence complexes" [M(L)2][M'X2(L)2]Y4 (M, M' = Pt, Pd, Ni; X = Cl, Br, I; L = neutral ligand; Y = counter ion), such as [Pt(en)2][PtCl2(en)2].

Chains can also be produced from metallo-organic precursors. For example, X{Fe}C4{Fe}X (X = I, NCMe, and N2; {Fe} = Fe[1,2-bis(diethylphosphino)-ethane)2]; C4 = alternating C single and triple bonds), these are used to form homometallic linkers that attach to Au electrons for electron transport.
