The structural topology of a 2D network defines its electronic structure.

Using the planar 1,8-naphthyridin-2(1H)-one (Hnpo) ligand, novel nonhelical HMSCs [MoM(npo)(NCS)] (M = Fe, Co, Ni) were synthesised and they exhibited high single-molecule conductance.

A dimeric molybdenum precursor and nickel ions are used to synthesize a symmetric heteropentanuclear complex, [MoNiMo(tpda)(NCS)]. This complex possesses unique structural features, as the four ligands are coordinated to the metal framework in a meso configuration. Furthermore, the central Ni ion is in a high spin state.
