Two ternary complexes of copper with acrylate and antipyrine, copper with α-methacrylate and antipyrine were synthesized and characterized by elemental analysis, infrared spectrum, electron reflection spectrum, ESR spectrum and temperature-dependent magnetic susceptibility The complex was identified as Cu2 A4 (C11H12 N2 O) 2, where A = CH2 = CHCOO-, CH2 = C (CH3) COO-, C11H12 N2 O = antipyrine. The crystal structure of Cu2 [CH2 = C (CH3) COO] 4 (C11H12 N2 O) 2 was determined. The crystal is monoclinic; P2 1 / n group; cell parameters: a = 1.2 0 2 6 4 (8) nm, b = 0 .876 0 4 (10) nm, c = 1.882 4 6 , β = 10 0 .80 2 (5) °; Z = 2; final deviation factor R = 0 .304. Cu has a distorted tetragonal pyramidal coordination environment in which two Cu are bridged by four α-methacrylates, and one antipyretic molecule at the end of Cu coordinates as O atom. Cu Cu has a center of symmetry, Cu Cu distance of 0.26 6 15 (3) nm. The study of the temperature-dependent magnetic susceptibility shows that Cu Cu has strong anti-ferromagnetic coupling between the two complexes
