In the title complex, [Ni(C(21)H(14)Br(2)N(2)O(2))], the Ni(II) atom is coordinated by the two imine N and two phenolate O atoms of the Schiff base ligand in a tetrahedrally distorted square-planar geometry. The Ni-N and Ni-O distances are within the ranges expected for Ni-Schiff base derivatives. Intermolecular C-H...O hydrogen bonds link the molecules into centrosymmetric dimers, forming R(2)(2)(12) (A) and R(2)(2)(10) (B) rings. These dimers combine to form a supramolecular ABAB... aggregate which propagates along the [100] direction.
在标题配合物[Ni(C₂₁H₁₄Br₂N₂O₂)]中,Ni(II)原子由席夫碱配体的两个亚胺氮原子和两个酚氧原子以四面体畸变的平面正方形几何构型配位。Ni-N和Ni-O距离在Ni-席夫碱衍生物预期的范围内。分子间的C-H...O氢键将分子连接成中心对称的二聚体,形成R₂²(12) (A)和R₂²(10) (B)环。这些二聚体结合形成沿[100]方向延伸的超分子ABAB...聚集体。
