Solvothermal Synthesis and Crystal Structure of a 18-Membered Macrocycle Schiff Base Dinuclear Copper(II) Complex: Cu-2(NO3)(4)(APTY)(4) (APTY=1,5-dimethyl-2-phenyl-4-{[(1E)-pyridine-4-ylmethylene]amino}-1,2-d ihydro-3H-pyrazol-3-one)

摘要

A new 18-membered macrocycle Schiff base dinuclear copper(II) complex: Cu-2(NO3)(4)(APTY)(4) (1) (APTY = 1,5-dimethyl-2-phenyl-4-{[(1E)-pyridine-4-ylmethylene] amino}-1,2-dihydro-3H-pyrazol-3-one), has been successfully synthesized by solvothermal treatment of Cu(NO3)(2)center dot 6H(2)O with APTY. Compound 1 crystallizes in the triclinic space group P-1 with cell parameters: a = 10.556(2) angstrom, b = 12.075(2) angstrom, c = 15.230(3) angstrom, alpha = 74.75(3), beta = 81.50(3), gamma = 70.60(3)degrees, V = 1762.7(6) angstrom(3), R1 = 0.0493, wR2 = 0.1400, Z = 1, D-calc = 1.455 g/cm(3), F( 000) = 798, S = 1.009. In the compound molecules, each of the six-coordinated Cu II atoms are bridged by APTY ligands into 18-membered macrocycle, and each the Cu2+ atoms exhibits a significantly distorted octahedral geometry. The crystal packing is stabilized by C-H center dot center dot center dot O hydrogen-bonding interactions into a three-dimensional supramolecular framework.
