“…This second step of the thermal analysis took place for crystal 2 at a temperature range of 100-119°C, with a These thermal decomposition results showed that crystals 1 and 2 were 2 new examples of Hofmann-type clathrates. Similar decomposition stages were observed for other Hofmann-type clathrates [5,33,[35][36][37][38][39].…”

Two new 2-dimensional cyanide-bridged coordination polymers [Zn(H 2 O) 2 Ni(CN) 4 6(H 2 O) and Zn(H 2 O) 2 Ni(CN) 4 3(C 4 H 8 O 2) ], which were similar to Hofmann-type clathrates, were synthesized based on [Ni(CN) 4 ] 2− and Zn 2+ as building blocks. These substances were synthesized as compounds in crystalline form. Thes tructures of the crystalline compounds were characterized via their spectral analyses. General information about the structures of the newly obtained Hofmann-type clathrates was obtained from their vibration spectra by considering significant changes in the vibration peaks of the cyanide group, water ligand molecule, and guest molecules (water and 1,4-dioxane). The thermal behavior of the Hofmann-type clathrates was investigated in the range of 25-500°C. In addition, experimental data on the magnetic properties of the Hofmann-type clathrates were obtained using the Gouy method under normal conditions. Information on the properties of the structures of the Hofmann clathrates was obtained by applying the single crystal diffraction technique. The asymmetric unit of the first Hofmann-type clathrate contained 1 Zn(II) ion, 1 Ni(II) ion, 1 cyanide ligand, 1 water ligand molecule, and 2 guest water molecules. The asymmetric unit of the second Hofmann-type clathrate contained 1 Zn(II) ion, 1 Ni(II) ion, 2 cyanide ligands, 1 water ligand molecule, and 2 half guest 1,4-dioxane molecules.

“…An increase of*25 cm -1 relative to free [Ni(CN) 4 ] 2-ion, which is observed in 1 and 2 (Table 4), is explained as a coupling of the M-N(NC) vibrational modes with C:N vibrations [53]. The characteristic t(CN) and d(NiCN) frequencies are similar to those known for Hofmann-type complexes and clathrates [51,[54][55][56][57], and indicate that the [M-Ni(CN) 4 ] n layers have been preserved. The presence of just one IR active (E u ) and two Raman active (A 1g ) and (B 1g ) CN stretching vibrations normally confirm the square planar environment around the [Ni(CN) 4 ] 2-ion [48].…”

“…When the aromatic ring nitrogen is involved in complex formation, certain ring modes, particularly in the 1,400-1,600 cm -1 region, increase in energy due both to coupling with M-N (ligand) bond vibrations [44][45][46] and alterations of the ring force field [47]. Analogous shifts on coordination were observed in pyridine [44], 4,4 0 -bipridyl [48], pyrimidine [49] and pyrazine [45,46,50] complexes and explained as a coupling of the internal modes of the aromatic molecule with the M-N vibrations [44,51]. The vibrational frequencies of the complexes are found to be …”

Two novel cyano-bridged heteropolynuclear complexes, [Zn(mprd) 2 Ni(l-CN) 4 ] n (1) and {[Cd(mprd) 2 Ni (l-CN) 4 ]Á2H 2 O} n (2), (mprd = 4-methylpyrimidine), have been synthesized and characterized by FT-IR spectroscopy, Raman spectroscopy, thermal analyses (TG, DTG and DTA) and elemental analyses. The crystal structure of the 1 was determined by X-ray single crystal diffraction. The complex crystallizes in the monoclinic, space group C2/c. The crystal structure of 1 consists of a corrugated 2D network in which the Zn(II) and Ni(II) atoms are linked by cyanide groups. The Ni(II) atom is four coordinate with four carbon atoms in a square-planar geometry; and, the Zn(II) atom is six coordinate with four cyanide-nitrogen and two mprd-nitrogen atoms with a distorted octahedral geometry. The shifts of the cyano stretching vibration are evidence for the formation of cyano bridges. Vibration assignments are given for all the observed bands and the spectral features support the structure of the polymeric complexes.
