Аннотация
Two new copper (II) complexes [Cu(2–Pic)2(4–NPA) 2] (1) and [Cu(2–Pic)2]×2H2O (2), where 2–Pic is 2–picolinic acid and 4–NPA is 4–nitrophenylamine, are synthesized hydrothermally and their crystal structures are determined and analyzed. Complex 1 is crystallized in the monoclinic system space group P21/c and complex 2 is in the triclinic system space group P–1. Single crystal X–ray analysis reveals that the coordination environments around the Cu atoms of two complexes are four-coordinated and six-coordinated respectively. Complex 1 forms a 2D layer of a supermolecular structure through hydrogen bonds, and complex 2 is a 1D stair-stepping polymer chain and two water molecules linked by a hydrogen bond intersperse among the chains.
