Two new hybrid iodoantimonates( iii ), (3-C 5 H 12 NO) 4 [Sb 4 I 16 ] · 2 H 2 O ( 1 , 3-C 5 H 12 NO + is 3-hydroxypiperidinium) and (4-C 5 H 12 NO) 4 [Sb 4 I 16 ] · 3 H 2 O ( 2 , 4-C 5 H 12 NO + is 4- hydroxypiperidinium), were synthesized. Their crystal structures were established. The anionic substructures of the new compounds are composed of the same tetranuclear complex anions [Sb 4 I 16 ] 4− . The differences in the structure of 3-hydroxypiperidine and 4-hydroxypiperidine are responsible for the differences in the supramolecular organization of the cationic substructures and in the packing of the structural units. The comparative analysis of hydrogen bonding systems in the structures of compounds 1 and 2 was carried out. The band gap width for compound 1 was estimated at 2.38 eV according to the direct band gap model and at 2.28 eV in terms of the indirect band gap model.
