The Schiff base ligand (1), C15H17NO crystallizes in the monoclinic space group P21/c witha=10.054(3),b=10.313(3), c=13.173(4)Å, β=107.42(4)°,V=1303.2(7)Å3,Z=4,Dx=1.159 g cm−3, and μ(MoKα)=0.674 cm−1. The C2-O1.23(1)Å and C3−C4 1.33(2)Åbond lengths are short, due to its quinoidal structure. In the Schiff base nickel complex (2), Ni(C16H18NO)2 the asymmetric unit is comprised of two half-complexes. It crystallizes in the triclinic space group$$Pbar 1$$witha=5.124(3),b=16.227(3),c=16.886(4)Å, α=95.47(8), β=96.00(1), γ=90.71(4)°,V=1389.6(9) Å3,Z=2,Dx=1.289 g cm−3, and μ(MoKα) =12.1 cm−1. The coordination of the Ni(II) ions are square planar with bond angles between 87.9(1) and 92.1(1)°. The Ni−O and Ni−N distances are 1.819(2), 1.922(2) and 1.823(2), 1.
