Synthesis, characterization and crystal structures of 2,4-di(2-aminopyridine)-6-methypyrimidine (dapmp), [Cu(dapmp)Cl-2] and [Cu(dapmp)(CH3COO)(2)]center dot H2O

摘要

The new ligand dapmp (1) has been synthesized and the reactions of CuCl2 . 2H(2)O and Cu(CH3COO)(2) . H2O with the new ligand in methanol afforded two crystalline polymorphic forms: [Cu(dapmp)Cl-2] (2) and [Cu(dapmp)(CH3COO)(2)] . H2O (3), where dapmp = 2,4-di(2-aminopyridine)-6-methylpyrimidine. Single crystal X-ray diffraction showed that (1) and (2) are each connected by hydrogen bonding to form a one-dimensional supermolecular compound and (3) is connected by hydrogen bonding to form a three-dimensional supermolecular compound.
