Synthesis, characterization, crystal structure and thermal analysis of a copper(II) mononuclear compound with 2,6-bis(3,5-dimethyl-N-pyrazolyl) pyridine (bdmpp) and selenocyanate as ligands

Abstract

A single crystal of the copper(II) compound, [Cu(bdmpp)(SeCN)(2)], 2, was obtained and its crystal structure was determined by X-ray diffraction methods. The complex was characterized by elemental, thermal and FTIR analysis. The FTIR analysis of the complex clearly shows the SeCN peaks at 2096 and 2061 cm(-1) which did not exist in the free organic ligand ( bdmpp). X-ray analysis showed that 2 crystallized in the monoclinic space group P2(1)/c. Cu(II) has a distorted trigonal bipyramidal coordination involving three N atoms from the ligand and two N atoms from the selenocyanate group.
