This work comprehensively investigated the coordination chemistry of a hexa -dentate neutral amine ligand, namely, N,N',N" - tris -(2- N -diethylaminoethyl)-1,4,7-triaza-cyclononane (DETAN), with group-1 metal cations (Li + , Na + , K + , Rb + , Cs + ). Versatile coordination modes were observed, from four-coordinate trigonal pyramidal to six-coordinate trigonal prismatic, depending on the metal ionic radii and metal's substituent. For comparison, the coordination chemistry of a tetra -dentate tris -[2-(dimethylamino)ethyl]amine (Me 6 Tren) ligand was also studied. This work defines the available coordination modes of two multidentate amine ligands (DETAN and Me 6 Tren), guiding future applications of these ligands for pursuing highly reactive and elusive s-block and rare-earth metal complexes.
