Abstract: The title compound, {[NdPt(CN)₄(NO₃)(C₁₅H₁₁N₃)(H₂O)₂]·CH₃CN·0.5C₁₅H₁₁N₃}_n, was isolated from solution as a one-dimensional coordination polymer. The Nd³⁺ site in the structure has a ninefold coordination with a distorted tricapped trigonal-prismatic geometry, while the Pt^II ion is coordinated by four cyanide groups in an almost regular square-planar geometry. Cis-bridging by the tetracyanidoplatinate anions links the Nd³⁺ cations, forming the one-dimensional chains. Additionally, each Nd³⁺ contains coordination by two water molecules, one tridentate 2,2':6',2''-terpyridine molecule, and one bidentate nitrate anion. 2,2':6',2''-Terpyridine and acetonitrile solvent molecules are incorporated between the chains, the former form -stacking interactions (average interplanar distance 3.33 Å) with terpyridine molecules located in the chains. Relatively long PtPt interactions [3.847 (1) Å] are observed in the structure. O-HN and O-HO hydrogen bonding interactions between the consituents consolidates the crystal packing.
