A systematic exploration of the Nd-Pt-Sn ternarysystem revealed a stunning wealth of compounds. Seven of the eightcompounds observed in the ternary system Pt/Sn/Nd can even be structurallyderived from the binary compounds Sn2Nd and Sn5Nd2 by adding Pt. The understanding of structure and bonding in intermetallicphasesstill lags behind that of molecular compounds. For that reason, exploringintermetallic phases and identifying structural patterns and relationshipsare particularly important for closing this knowledge gap. In particular,here we report on the addition of increasing amounts of platinum to similar to 2:1 mixtures of tin and neodymium, which yields eight ternaryPt/Sn/Nd compounds, four of which have not been reported before. Interestingly,except for PtSnNd (1), all observed ternary phases ofthe system can be derived from the binary compounds Sn2Nd and Sn5Nd2 by adding Pt to the composition(s),as they lie on or close to two lines: Sn2Nd-Pt (Pt0.21(1)Sn2Nd (2), PtSn2Nd(3), Pt1.33Sn2Nd (4), Pt2-x Sn2+x Nd (x = 0.27(3), 5), and Pt3Sn2Nd (6)) or Sn5Nd2-Pt (Pt1.5Sn5-x Nd2 (x = 0.16(2), 7) and Pt3Sn5Nd2-x (x = 0.161(8), 8)). While theintroduction of increasing amounts of Pt to the binaries Sn2Nd and Sn5Nd2 leads to stepwise changes inthe coordination environment of Nd, Pt preserves its coordinationover the entire system in the form of interpenetrating bipyramidal{PtSn5Nd5} clusters.
