Four isotypic one‐dimensional coordination polymers (CP) were synthesized using the group 13 metal halides AlBr3, GaCl3, GaBr3, and InI3 and the tridentate ligand 2,4,6‐tri(4‐pyridyl)‐1,3,5‐triazine (tpt) serving as bidentate linker. The neutral one‐dimensional CPs 1∞[AlBr3(tpt)], 1∞[GaCl3(tpt)], 1∞[GaBr3(tpt)], and 1∞[InI3(tpt)] are constituted by zigzag‐shaped chains in the crystal structure, in which one coordination site of the tpt ligand remains uncoordinated. All CPs were characterized by SCXRD, PXRD, simultaneous DTA/TG, elemental‐analysis and IR spectroscopy. Furthermore, three complexes of the composition [(AlBr3)3(tpt)], [(GaCl3)3(tpt)], and [(GaBr3)3(tpt)] were structurally characterized by SCXRD, being preliminary and side products of the formation of the coordination polymers.
