The structure of precursors is used to control the formation of six possible structural isomers that contain four structural units of PbSe and four structural units of NbSe 2 : [(PbSe) 1.14 ] 4 [NbSe 2 ] 4 , [(PbSe) 1.14 ] 3 [NbSe 2 ] 3 [(PbSe) 1.14 ] 1 [NbSe 2 ] 1 , [(PbSe) 1.14 ] 3 [NbSe 2 ] 2 [(PbSe) 1.14 ] 1 [NbSe 2 ] 2 , [(PbSe) 1.14 ] 2 [NbSe 2 ] 3 [(PbSe) 1.14 ] 2 [NbSe 2 ] 1 , [(PbSe) 1.14 ] 2 [NbSe 2 ] 2 [(PbSe) 1.14 ] 1 [NbSe 2 ] 1 [(PbSe) 1.14 ] 1 [NbSe 2 ] 1 , [(PbSe) 1.14 ] 2 [NbSe 2 ] 1 [(PbSe) 1.14 ] 1 [NbSe 2 ] 2 [(PbSe) 1.14 ] 1 [NbSe 2 ] 1 . The electrical properties of these compounds vary with the nanoarchitecture. For each pair of constituents, over 20 000 new compounds, each with a specific nanoarchitecture, are possible with the number of structural units equal to 10 or less. This provides opportunities to systematically correlate structure with properties and hence optimize performance.
