Abstract A new motif for infinite metal atom wires with tunable compositions and properties is developed based on the connection between metal paddlewheel and square planar complex moieties. Two infinite Pd chain compounds, [Pd 4 (CO) 4 (OAc) 4 Pd(acac) 2 ] 1 and [Pd 4 (CO) 4 (TFA) 4 Pd(acac) 2 ] 2 , and an infinite PdPt heterometallic chain compound, [Pd 4 (CO) 4 (OAc) 4 Pt(acac) 2 ] 3 , are identified by single‐crystal X‐ray diffraction analysis. In these new structures, the paddlewheel moiety is a Pd four‐membered ring coordinated by bridging carboxylic ligands and μ 2 carbonyl ligands. The planar moiety is either Pd(acac) 2 or Pt(acac) 2 (acac=acetylacetonate). These moieties are connected by metallophilic interactions. The results showed that these one‐dimensional metal wire compounds have photoluminescent properties that are tunable by changing ligands and metal ions. 3 can also serve as a single source precursor for making Pd 4 Pt bimetallic nanostructures with precise control of metal composition.
