In the title complex, [Co(C(26)H(20)N(2)O(4))(NCS)]·C(4)H(10)O·CH(2)Cl(2), the penta-coordinated Co(III) atom exhibits a distorted square-pyramidal geometry with an N,N',O,O' tetra-dentate Schiff base ligand in the basal plane and one thio-cyanate ligand at the apical site. The diethyl ether mol-ecule is located in a cavity provided by four O atoms of the ligand with weak C-H⋯O inter-actions, generating two short O⋯O contact distances [2.766 (3) and 2.745 (3) Å] between the diethyl ether mol-ecule and the ligand. The crystal structure is stabilized by the weak C-H⋯O and C-H⋯N inter-actions and π-π inter-actions between the naphthyl ring system and the benzene ring [centroid-centroid distance = 3.657 (5) Å] and between the two naphthyl ring systems [centroid-centroid distance = 4.305 (2) Å].
在标题配合物[Co(C₂₆H₂₀N₂O₄)(NCS)]·C₄H₁₀O·CH₂Cl₂中,五配位的Co(III)原子呈现出扭曲的四方锥几何构型,其底面为一个N,N',O,O'四齿席夫碱配体,顶端为一个硫氰酸根配体。二乙醚分子位于由配体的四个O原子提供的空腔中,存在弱的C-H⋯O相互作用,在二乙醚分子与配体之间产生了两个较短的O⋯O接触距离[2.766 (3)和2.745 (3) Å]。晶体结构通过弱的C-H⋯O和C-H⋯N相互作用以及萘环体系与苯环之间的π-π相互作用[质心-质心距离 = 3.657 (5) Å]和两个萘环体系之间的π-π相互作用[质心-质心距离 = 4.305 (2) Å]得以稳定。
