“…There are no similar polymeric cadmium(II) complexes with either picolinamide, nicotinamide, or isonicotinamide in the literature. However, two dimeric cadmium(II) complexes with the same antiparallel N,O′-bridging of nicotinamide are known [20,21]. The asymmetric unit of [Cd(H 2 O) 3 (nia) 3 ](ClO 4 ) 2 •nia (3) consists of a cadmium(II) ion, three coordinated water molecules, three coordinated nicotinamide molecules, two uncoordinated perchlorate ions, and a cocrystallized nicotinamide molecule (Figure 1c).…”

Three novel cadmium(II) coordination compounds, the dimeric [Cd(CH3COO)2(nia)2]2 (1), the polymeric {[Cd(nia)4](ClO4)2}n (2), and the monomeric [Cd(H2O)3(nia)3](ClO4)2·nia (3), were prepared in the reactions of the nicotinamide (pyridine-3-carboxamide, nia) with the corresponding cadmium(II) salts. All prepared compounds were characterized by elemental analyses, FT-IR spectroscopy, TGA/DTA, and single crystal X-ray analysis. The impact of anions (acetate, perchlorate) and solvent used on the dimensionality of cadmium(II) complexes and the cadmium(II) coordination environment was investigated. The bridging capabilities of acetate ions enabled the formation of dimers in the crystal structure of 1. It was shown that the dimensionality of perchlorate complexes depends on the solvent used. The coordination polymer 2 is isolated from an ethanol solution, while monomeric compound 3 was obtained by using a water/ethanol mixture as a solvent. The pentagonal-bipyramidal coordination of cadmium(II) was found in the presence of chelating and bridging acetate ions in 1. In the presence of non-coordinating perchlorate anions in 2 and 3, the coordination geometry of cadmium(II) is found to be octahedral. The supramolecular amide-amide homosynthon R22(8) was preserved in the hydrogen-bonded frameworks of all three compounds.
