Crystal structure of bis[dihydrobis(pyrazol-1-yl)borato-κ2N2,N2′](1,10-phenanthroline-κ2N,N′)zinc(II)

Abstract

The asymmetric unit of the title compound, [Zn(C6H8N4B)2(C12H8N2)], comprises one half of a ZnII cation (site symmetry 2), one dihydrobis(pyrazol-1-yl)borate ligand in a general position, and one half of a phenanthroline ligand, the other half being completed by twofold rotation symmetry. The ZnII cation is coordinated in form of a slightly distorted octahedron by the N atoms of a phenanthroline ligand and by two pairs of N atoms of symmetry-related dihydrobis(pyrazol-1-yl)borate ligands. The discrete complexes are arranged into columns that elongate in the c-axis direction with a parallel alignment of the phenanthroline ligands, indicating weak π–π interactions.
