Investigation of the FT-IR Spectroscopic Properties of M(4-Pyridinecarboxaldehyde)Ni(CN)4.nG Hofmann Type Clathrates (M = Ni, Cd and G = 1,4-Dioxane)

36018

In this study, clathrate of 4-pyridinecarboxaldehyde tetracyanonickel-dioxane, given by the formula M(4-Pyridinecarboxaldehyde)Ni(CN)4 nG (m = Ni, Cd and G = 1,4-dioxane), is obtained for the first time through chemical methods. The FT-IR spectroscopic data in the region of (3000–400) cm^-1 was recorded and the IR vibrational modes frequencies were given and explained in detail. The spectral analyzes results of the newly synthesized clathrate of 4 -pyridinecarboxaldehyde tetracyanonickel- dioxane suggests that these clathrates are new examples of the Hofmann-type dioxane clathrates. In our study, the Hofmann-type dioxane clathrates formed by bounding electrons of nitrogen-donor atom of pyridine ring and electrons of oxygen-donor atom of aldehyde group (-CH=O) of 4-pyridinecarboxaldehyde ligand molecule to transition metal atoms consist of the corrugated |M–Ni(CN)4| polymeric layers which are held in parallel through the chain of (–M–4PCA–M–).
