In the neutral complex mol-ecule of the title compound, fac-[CrCl3(tpa)] [tpa is tris-(pyridin-2-yl)amine; C15H12N4], the Cr(III) ion is bonded to three N atoms that are constrained to a facial arrangement by the tpa ligand and by three chloride ligands, leading to a distorted octa-hedral coordination sphere. The average Cr-N and Cr-Cl bond lengths are 2.086 (5) and 2.296 (4) Å, respectively. The complex mol-ecule is located on a mirror plane. In the crystal, a combination of C-H⋯N and C-H⋯Cl hydrogen-bonding inter-actions connect the mol-ecules into a three-dimensional network.
在标题化合物fac-[CrCl₃(tpa)]（tpa为三（吡啶-2-基）胺；C₁₅H₁₂N₄）的中性络合物分子中，Cr(III)离子与三个N原子键合，这些N原子通过tpa配体和三个氯配体被限制在一个面式排列中，从而形成一个扭曲的八面体配位球。Cr-N和Cr-Cl的平均键长分别为2.086(5) Å和2.296(4) Å。络合物分子位于一个镜面平面上。在晶体中，C-H⋯N和C-H⋯Cl氢键相互作用的组合将分子连接成一个三维网络。
