Abstract
A novel trinuclear nickel(II) ONO pincer complex [Ni(pydc)2]2[Ni(H2O)5]·2H2O·2(C6H15N) (1) (H2pydc = 2,6-pyridinedicarboxylic acid) is synthesized by the reaction between Ni(OAc)2 and H2pydc in acetonitrile in the presence of triethylamine. A detailed study through single crystal XRD reveals that the compound crystallizes in the triclinic space group P-1 with cell parameters a = 11.6646(3) Å, b = 14.0999(4) Å, c = 16.4633(5) Å, α = 80.189(2)°, β = 75.539(2)°, γ = 67.017(2)°. Both terminal Ni(II) centers are coordinated to two ONO pincer ligands (pydc) bridged by the nickel penta aqua unit. Further, triethyl ammonium neutralizes the trinuclear complex.
