Two copper(II) complexes with 4-benzoylpyridine ligand: Synthesis, crystal structure and luminescent properties
摘要:
Two new copper(II) complexes Cu(NCS)(2)(4-Bzpy)(2) (1) and Cu(NO3)(2)(4-BzPY)(4) (2) (4-Bzpy = 4-benzoylpyridine) have been synthesized and characterized by IR. UV, elemental analysis and X-ray crystallography. Cu(II) atom has a square planar environment for 1 and an distorted octahedral environment for 2, respectively. In solid state there are C-H...pi interactions and C-H...S hydrogen bonds between adjacent molecules in complex 1. The molecule of complex 2 is further connected by multiform pi-pi interactions, C-H...pi interactions and C-H...O hydrogen bonds to form a three-dimensional supramolecular structure. The luminescent properties of the complexes 1 and 2 were both investigated in H2O solution and in solid state at room temperature, respectively. (C) 2011 Elsevier B.V. All rights reserved.
