Abstract

N,N-bis(2-quinolinylmethyl)benzylamine (1) was synthesized under basic conditions from a pseudo-three-component reaction between benzylamine and two molecules of 2-(quinolinylmethyl)chloride, resulting in the formation of two N–C bonds in a single step. Compound (1) crystallizes in the triclinic system of the P-1 space group. The unit cell comprises a dimer of 1, in which the monomers are linked by two complementary hydrogen bonds between N1 and H′1–C′1 of another molecule. The dimers form chains along the a-axis through intermolecular interactions between the N′2 acceptor atoms and C″17 donors from molecules in the nearest neighboring dimer. These interactions form extended sheets of the dimers of 1, along the ab plane. The quinolinylmeth-2-yl groups of 1 lie in almost orthogonal planes and their N1/2(q) donor atoms are away from the apical amino N3 atom.

Summary

Introduction

Bis(2-pyridinylmethyl)amines (bpmas) (type I) and their closely related analogues, bis(2-quinolinylmethyl)amines (bqmas) (type II) are versatile tridentate N-donor ligands that form mononuclear metal complexes with flexible five-membered chelates [1,2,3,4,5,6,7]. Bis(2quinolinylmethyl)benzylamine (1), a derivative of the bqma ligands with an appended benzyl group at the amine position, was first reported by Kryatov et al [1]. Its crystal structure has not been reported to date. In that report of Kryatov et al [1], 1 was used together with other iso-structural ligands for stabilizing dinuclear complexes with a common Fe(II)(μ-OH) core. Kunishita et al [2] used this ligand for the synthesis of Cu(II) complexes. Li et al [5] synthesized monomeric Ni(II)
