Coordination compounds of polydentate nitro-gen ligands with metals are used extensively in research areas such as catalysis, and as models of complex active sites of enzymes in bioinorganic chemistry. Tris(2-pyridyl-meth-yl)amine (TPA) is a tripodal tetra-dentate ligand that is known to form coordination compounds with metals, including copper, iron and zinc. The related compound, tris-[(6-bromo-pyridin-2-yl)meth-yl]amine (TPABr), CHBrN, which possesses a bromine atom on the 6-position of each of the three pyridyl moieties, is also known but has not been heavily investigated. The mol-ecular structure of TPABr as determined by X-ray diffraction is reported here. The TPABr molecule belongs to the triclinic, space group and displays interesting intermolecular Br⋯Br interactions that provide a stabilizing influence within the molecule.
多齿氮配体与金属的配位化合物广泛应用于催化等研究领域，并作为生物无机化学中酶的复杂活性位点模型。三（2-吡啶甲基）胺（TPA）是一种三脚架四齿配体，已知它能与包括铜、铁和锌在内的金属形成配位化合物。相关化合物三[（6-溴吡啶-2-基）甲基]胺（TPABr），CHBrN，在三个吡啶部分的每个6位上都有一个溴原子，也为人所知，但尚未得到深入研究。本文报道了通过X射线衍射测定的TPABr的分子结构。TPABr分子属于三斜晶系空间群，显示出有趣的分子间Br⋯Br相互作用，这种相互作用在分子内提供了稳定作用。
