  Synthesis, crystal structure, magnetism and specific heat of a new copper(II) compound with p-aminobenzoic acid

  摘要：

  In this work we present the synthesis, crystal structure, magnetic and specific heat measurements of a new monomeric copper(II) compound, in which the metal ion is coordinated to two p-aminobenzoic acid (PABA) molecules and two chloride ions. This compound with formula [CuCl2(C7H7NO2)(2)] presents a peculiar crystalline structure packing, showing hydrogen-bonds between carboxylic acid groups and short N-H center dot center dot center dot Cl contacts resulting in a polymeric character in two dimensions. In the third direction, Cu center dot center dot center dot Cl close contacts between neighboring molecules are responsible for a chain-like magnetic behavior. Considering the simplicity of the molecular unit, the magnetic properties show surprising results: below 6.4 K a hysteresis cycle appears in the magnetization curves as well as a splitting between low field ZFC-FC measurements. No phase transition to a long-range order was observed by specific heat measurement. (C) 2011 Elsevier B.V. All rights reserved.
