Abstract: Novel three-dimensional (3D) coordination polymer {[Ho2(μ3-ATA)2(μ4-ATA)(H2O)4]·2DMF·1/2H2O}n (1), built from Ho(III) cations and 2-aminoterephthalate anionic ligands (ATA2 −) was prepared and studied. The compound 1 contains 1D structural channels with the size 4.1 × 6.8 Å2, which propagate along b crystallographic axis. The channels are filled with the solvent molecules. The Ho(III) atom is eight-coordinated with distorted square anti-prismatic geometry. Complex was characterized by single crystal X-ray diffraction, thermogravimetry coupled with simultaneous evolved gas analysis using mass spectrometry (TG/DTG–DTA–EGA), powder X-ray diffraction (PXRD), infrared spectroscopy (FT-IR), solid-state UV–VIS spectroscopy and nitrogen adsorption at 77 K. After the desolvation the 1D structural channels collapse. The process is accompanied by structure transformation, however, according to the TG–DTA–EGA results, the Ho–ATA polymeric framework is stable up to 450 °C.
