Complex [FeL2(NCS)(2)]center dot H2O (L = 3,5-di(pyrimidin-2-yl)-4H-1,2,4-triazol-4-amine) was prepared as the first example of complex compounds of transition metals with 3,5-di(pyrimidin-2-yl)-4H-1,2,4-triazol-4-amines. The coordination core of the iron atom is a distorted octahedron FeN6. In the range 80-300 K the complex is high-spin, mu(eff) similar to 5.3 MB. The parameter of the crystal field splitting, 10Dq, for [FeL2(NCS)(2)]center dot H2O is similar to 10800 cm(-1).
