Azido and Thiocyanato-Bridged Polymeric Copper(II) Complexes [CuL(μ1,3-N3)]n·2nH2O and [CuL(μ1,3-NCS)]n: Synthesis and Structures
摘要:
A new azido-bridged polymeric copper(II) complex, [CuL((1,3)-N-3)](n)center dot 2nH(2)O (1), and a new thiocyanato-bridged polymeric copper(II) complex, [CuL((1,3)-NCS)](n) (2) (L = 4-methoxy-2-[(2-morpholin-4-ylethylimino)methyl]phenolate), have been prepared and structurally characterized by elemental analysis, IR spectra, and single-crystal X-ray determination. Each Cu atom in the complexes is coordinated by three donor atoms of Schiff bases and by two atoms of the pseudohalide ligands, forming a square pyramidal geometry. Azide and thiocyanate anions are preferred bridging groups for the construction of polymeric copper complexes with Schiff bases.
