High-spin complex [FeL2(NCS)2]·H2O [L = 3,5-di(pyrimidin-2-yl)-4H-1,2,4-triazol-4-amine]: Synthesis and properties

Complex [FeL 2 (NCS) 2 ]·H 2 O (L = 3,5-di(pyrimidin-2-yl)-4 H -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)-4 H -1,2,4-triazol-4-amines. The coordination core of the iron atom is a distorted octahedron FeN 6 . In the...

Zusammenfassung:Complex [FeL 2 (NCS) 2 ]·H 2 O (L = 3,5-di(pyrimidin-2-yl)-4 H -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)-4 H -1,2,4-triazol-4-amines. The coordination core of the iron atom is a distorted octahedron FeN 6 . In the range 80–300 K the complex is high-spin, μ eff ∼ 5.3 MB. The parameter of the crystal field splitting, 10 Dq , for [FeL 2 (NCS) 2 ]·H 2 O is ∼10800 cm −1 .
