Abstract: 
The one-dimensional coordination polymer (1)(infinity)[SbCl3(pyz)] (1) and the three-dimensional frameworks (3)(infinity)[Sb2Cl6(pyz)(3)] (2) and (3)(infinity)[Sb2I6(pyz)(3)] (3) were obtained from SbX3 (X: Cl, I) and pyrazine (pyz). These coordination polymers are, to the best of our knowledge, among the first Sb-based coordination polymers constructed from antimony halides and N-donor ligands. While the Sb3+-cations in 1 are coordinated in a square-pyramidal coordination sphere indicating a stereochemically active lone-pair, no stereochemically active Sb-lone-pair is present in 2 and 3 having octahedral coordination spheres around Sb-III. Since 2 can be obtained by heating of 1, the character of the Sb-lone-pair in 1 can be changed by thermal treatment. Thereby the interlinkage is increased via an additional pyrazine molecule resulting in the octahedral coordination in 2.
