ABSTRACT. Three new cyano-bridged heteronuclear polymeric complexes, [Cu(etim) 2-coordinated to the adjacent M(II) ions and three nitrogen atoms of the etim ligands. The Cd(II) ion of the Cd-Ni-etim complex is six-coordinate, completed with the two nitrogen atoms of the etim ligands and the four nitrogen atoms from bridging cyano groups. Polymeric structures of the Cu-Ni-etim and the Zn-Ni-etim complexes are 1D coordination polymer, while complex the Cd-Ni-etim presents a 2D network. The thermal decompositions in the temperature range 30-700 C of the complexes were investigated in the static air atmosphere.

“…Shifts to high frequencies are thought to occur due to mechanical coupling between the internal vibration modes of the tetracyano nickelate group and the M-NC vibrations. 18,37 In the IR spectrum of 2, the ν(CN) stretching vibration frequencies are observed at 2128 and 2169 cm -1 (Table 2). These vibration frequencies are higher, around 8 and 49 cm -1 , than those for K 2 [Ni(CN) 4 ]•H 2 O salt.…”

“…[M(CN) 4 ] 2-(M(II) = Ni, Pd or Pt), have been widely used as building blocks of Hofmann type structures. 18,19,21,22,23 The vibrational spectroscopy is extensively used in the determination of the structures of Hofmann type complexes because cyano ligand gives sharp and intense ν(CN) stretching vibration between 2200 and 2100 cm -1 in the infrared (IR) and Raman spectra. 18,19,20,24 This paper reported the synthesis and characterisation of the cyano-bridged transition metal complexes with N,N'diethyl thiourea.…”

New cyano bridged transition metal complexes, [Cu(detu)4Ni(CN)4]-2H2O (1) and [Zn(H2O)(detu)Ni(CN)4]-2H2O (2) (detu = N, N' diethyl thiourea) have been synthesised in powder form. Their structures were illuminated by using spectroscopic, thermal and elemental analysis techniques. The nickel atom exhibits square planar geometry in these complexes by coordinating with the cyano group's nitrogen atoms. The copper atom of 1 is six coordinated with two bridging cyano groups and four detu ligands. In contrast, the zinc atom of 2 is six coordinated with four bridging cyano groups, one detu ligand and one aqua ligand. In addition, the structure of 2 is formed from polymeric layers of |Zn-Ni(CN)41 „ with the detu and aqua ligands bonded to the zinc atom. Thermal stabilities and decomposition products of 1 and 2 were examined in the static air atmosphere between 30 and 900 °C. Keywords: btetracyanonickelate(II) complex, N,N'-diethyl thiourea, cyano-bridged complex, vibration spectra, thermal analysis.
