摘要

The investigation into synthesizing new metal organic compounds with the general formula Cu(S-pyrazine)X2 using monosubstituted pyrazines has led to the generation of a new family of compounds Cu(S-pyrazine)2X2 with similar structure and magnetic properties. The bis(S-pyrazine)dihalocopper(II) compounds [where S = Cl, CN, OCH3, andOCH2CH3 and halide = Cl or Br] have been characterized by IR, powder X-ray diffraction, single-crystal X-ray diffraction, and temperature dependent magnetic susceptibility. The bis(chloropyrazine)dihalocopper(II) compounds crystallize in the monoclinic space group P21 while the methoxy and ethoxy analogues crystallize in the triclinic space group Pˉ1. This structurally related family of compounds exhibit antiferromagnetic interactions with exchange constants of approximately -25 K for the chloride analogues and -50 K for the bromide analogues.
