Synthesis X-Ray Structures, and Magnetic Properties of [Cu2(piv)4(Et3N)2] and [Cu6 (piv)6 (EtO)6 ] (Hpiv = Pivalic Acid): Role of Base for Dinuclear Adduct and Oligonuclear Formation

Copper(II) pivalate adduct with triethylamine, [Cu 2(piv)4 (Et3N) ] (Hpiv = pivalic acid), and cyclic hexanucicar copper(ll) complex, [Cu 6 (piv) 6(EtO) 6 ]. have been synthesized and characterized by X-ray crystallography and magnetic susceptibility measurement.
