Synthesis, Crystal Structure, and Biological Activity of a New Cu(I) Complex of the N-Phenyl-N′-(2-nitrobenzoyl)-thiourea

Abstract

The complex bis(μ-sulfur)-sulfur-[N-phenyl-N′-(2-nitrobenzoyl)-thiourea]copper (I) was obtained from the reaction between the N-phenyl-N′-(2-nitrobenzoyl)-thiourea(HL) and copper(II). The compound was characterized by IR and ¹H NMR, ¹³C NMR spectroscopy and its structure was determined by single crystal X-ray diffraction. The complex is binuclear with two copper(I) ions coordinated by a terminal sulfur, two bridging sulfurs, and a HL molecule. In addition, the compound is also a considerable plant-growth regulator.
