Mononuclear zinc(II) complexes of N,N′-bis(2-hydroxy-4-nitrophenylmethyl)-N,N′-bis(2-pyridylmethyl)-1,n-alkanediamines

Reaction of the symmetrical proligand HL4 with zinc(II) salts has given mono- and di-nuclear metal complexes. The structure of a mononuclear complex, [ZnL4], which crystallises in the triclinic space group P1 (Ci1, No. 2) with unit cell parameters a=9.3910(10), b=9.4959(10), c=15.9380(16) Å, α=96.938(2)°, β=97.097(2)°, γ=100.082(2)°, has been determined.
