摘要: Abstract Phenoxo-bridged complexes [M(μ-L)Na(ClO4)(CH3OH)] (M = Cu(II) (1) and Ni(II) (2)) (H2L = N,N′-bis(3-methoxysalicylidenimino)-1,3-diaminopropane, C6H3(OMe)(OH)-CH = N-(CH2)3-N = CH-C6H3(OMe)(OH)) are structurally characterised by single-crystal X-ray diffraction study. M(II) appears in the square-plane geometry with MN2O2 coordination sphere, while sodium ion exists NaO6 distorted octahedral environment. The molecules pack solid-state forming three-dimensional arrays through C–H- - -O, O–H- - -O, C–H- - -π, π- - -π interactions. spectral redox properties theoretically explained DFT computation of optimised complexes.
