In order to evaluation the effects of ultrasonic irradiations, concentration of initial reagents and reaction time on formation [Cu-4(MBT)(4)]. or [Cu-6(MBT)(6)] copper(I) metal-organic nanomaterials, [HMBT = 2-Mercaptobenzothiazole], we designed some experiments and synthesized six samples under different conditions. These nanostructures were characterized by IR spectroscopy, X-ray powder diffraction (XRD) and Scanning Electron Microscopy (SEM). It seems that the tetranuclear cluster of [Cu-4(MBT)(4)] (2) is the kinetically stable product which is formed at the initial time of the reaction and as the time went, it converts to thermodynamically stable product of [Cu-6(MBT)(6)] (1) with hexanuclear cluster unit. In the samples which synthesized with low concentration of initial reagents, against to those synthesized with high concentration of initial reagents, the ultrasonic irradiation does not have any effect on formation of any special morphology.
