Abstract
This study demonstrates that controlling intra-cluster ligand interactions is important to obtain an assembled structure with the desired connecting structures.

We found the following four points about thiolate (SR)-protected gold–platinum alloy (Au4Pt2) clusters ([Au4Pt2(SR)8]0); (1) [Au4Pt2(SR)8]0 is a metal cluster that can be used as a building block to form one-dimensional (1D) connected structures (1D-CS) via intercluster Au–Au bonds; (2) all [Au4Pt2(SR)8]0 clusters have similar structures, the intra-cluster ligand interactions vary depending on the ligand structure
We demonstrate that it is necessary to control the intra-cluster ligand interactions in the formation of the 1D-connected structures composed of ligand-protected metal clusters, which is important for their application in devices and to obtain new physical properties and functions
Summary
Shinjuku-ku, Tokyo 162-8601, Japan † Electronic supplementary information (ESI) available: Experimental section, bond lengths, the values of HOMO–LUMO gap, additional mass spectra, photographs of crystals, XPS spectra, enantiomer, additional theoretical results crystal data. These results demonstrate that we need to design intra-cluster ligand interactions to produce 1D-CS with desired connecting structures. We demonstrate that it is necessary to control the intra-cluster ligand interactions in the formation of the 1D-connected structures composed of ligand-protected metal clusters, which is important for their application in devices and to obtain new physical properties and functions.
