The 2‐phenyl‐2‐(1‐hydroxyiminoethyl)‐1,2,3,4‐tetrahydroquinazoline (HL) and its Ni II complex have been prepared and characterized by spectral method (FT‐IR, NMR ( 13 C and 1 H), UV‐vis.), elemental analysis, magnetic susceptibility and thermal analysis (TG, DTA) techniques. The crystal structures of HL and Ni II complex were also determined by the single crystal X‐ray diffraction. The HL and Ni II complex crystallizes in the monoclinic and triclinic, space groups P 2 1 /c and $P{\bar 1}$ , respectively. The complex was occurred by the elimination of 1 mole of 2‐aminobenzylamine from the 2 moles of the HL after the ring opening reaction by the Ni II attack. Crystallographic study reveal that Ni II atom has a square planer geometry being coordinated by four nitrogen atoms of HL. Two thermal processes of the HL and Ni II complex can occur in TG and DTA curves.
