چکیده انگلیسی
Micro and nano-structures of a new mixed-ligand Zn(II) fumarate metal-organic polymer, {[Zn(tptz)(fum)].DMF}n (1), (tptz = 2,4,6-tris(2-pyridyl)-s-triazine, fum = fumarate, DMF = N,N-dimethylforamide), were synthesized by sonochemical method. These new micro and nano-structures were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), IR spectroscopy and elemental analyses. Compound 1 was structurally characterized by single-crystal X-ray diffraction and consists of the primary unit of [Zn(tptz)(fum)]. Self assembly between the units of [Zn(tptz)(fum)] from Zn-O bonds results in the formation of a one-dimensional zinc(II) coordination polymer. The ZnII-ion in compound 1 has ZnO2N3 coordination sphere with a trigonal bipyramidal molecular geometry. Compound 1 was synthesized by ultrasound irradiation under different concentrations and times. The microrods structure of compound 1 with increasing of concentration and ultrasound radiation time were synthesized as nanoparticles structure successfully. So ultrasound radiation change morphology from microrods to nanoparticles.
