-Bridging by the tetracyanidoplatinate(II) anions links the Yb
3+
cations, forming chains. Additionally, each Yb
3+
is coordinated by two water molecules, one bidentate nitrate anion, and one tridentate 2,2′:6′,2′′-terpyridine molecule. O—H⋯N hydrogen-bonding interactions are found between adjacent chains and help to consolidate the crystal packing. In addition, π–π stacking interactions exist between the terpyridine ligand and the two corresponding terpyridine ligands along the adjacent chain (average interplanar distance = 3.667 Å). Moderate Pt⋯Pt interactions [3.5033 (4) Å] are observed in the structure. |
