Crystal Structure of a Coordination Polymer Cation of {[Ni(NO₃)(H₂O)₂(btp)]⁺}_∞ Bridged by Two btp Ligands (btp = 2,6-bis(N′-1,2,4-triazolyl)pyridine)

抄録

The btp ligand bridges Ni(II) ions to form a polymeric compound; further, two water ligands and a dangling btp ligand are also coordinated to Ni(II) ions. The coordination geometry of the Ni(II) ion is distorted octahedral. There is a hydrogen bond between a water ligand and a non-coordinated nitrate counterion (O1…O43 2.734(1)Å).
