Abstract

A new dinuclear iron nitrosyl complex [Fe(2)(C(14)H(12)N(3)S)(2)(NO)(4)] (1) (C(14)H(12)N(3)S = 2-mercapto-1-[2-(4-pyridyl)-ethyl]-benzimidazolyl) has been obtained by the reaction of Fe(NO)(2)(CO)(2) with 2-mercapto-1-[2-(4-pyridyl)-ethyl]-benzimidazole in CH(3)OH under moderate condition. Complex 1 was characterized by IR, UV-vis, electrochemistry and single crystal X-ray diffraction. IR spectrum displays two strong characteristic NO stretching frequencies (nu(NO)) in solution and in solid state. Cyclic voltammetry shows one irreversible, two quasi-reversible and two reversible one-electron reductions and irreversible oxidizations. This result is consistent with the fact that complex 1 is very unstable and ready to lose NO in the air. As showing in the single crystal X-ray diffraction, complex 1 forms a "chair-shape" structure by the connections of two iron centers and S-C-N frames of benzimidazole. The dihedral angle of benzimidazole ring and 2Fe-2S plane is 73.6 degrees . The crystal data are the following: 1, monoclinic, space group P2(1)/c, a = 10.43940(10) A, b = 16.0900(2) A, c = 10.13240(10) A, alpha = 90 degrees , beta = 111.0940(10) degrees , gamma = 90 degrees , V = 1587.89(3) A(3), Z = 4.

Anthelmintics

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
