Synthesis, IR spectrum, thermal property and crystal structure of cyano-bridged heteronuclear polymeric complex, [Cd(teta)Ni(μ-CN)2(CN)2] · 2H2O

“…There remains still much to be explored in the crystal engineering of Hofmann-type and analogous structures that are built by the CN-linkages among square-planar or tetrahedral tetracyanometallate(II) and octahedral metal(II) ligated with complementary ligands [1]. There are currently several successful examples of self-assembly towards the construction of cyanobridged complexes [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], in which cyanometallate anions, e.g. Cd(CN) 2 , Ni(CN) 2 and Pd(CN) 2 , behave as bridging moieties to build a multidimensional structure with a second coordination centre, and the resulting complexes demonstrate unique magnetic, host-guest and other properties [7].…”

“…The intramolecular Cu(1)Á Á ÁCu(1a) distance is 9.7396 (8) A A, whereas the shortest intermolecular CuÁ Á ÁCu distance is equal to 6.9731 (5) A A. The next four intermolecular CuÁ Á ÁCu distances are shorter than the intramolecular CuÁ Á ÁCu distance: 7.8313(5), 8.1078(6), 8.8515(6) and 9.2032 (6) A A. …”

“…The number of structural studies on molecular tetracyanonickelates (2-) [16,17]. On the contrary, a variety of multidimensional structures have been obtained in which [Ni(CN) 4 ] 2À forms a tetra-monodentate bridge (by using of all the N-atoms) [11,12] or a di-monodentate bridge (by using of two N-atoms of trans- [6][7][8]10] or cis-CN groups [9,[15][16][17]). Recently, the T-type three-bonded coordination [13] and monodentate ligation [14,15] of [Ni(CN) 4 ] 2À to copper(II) ions have also been reported.…”

“…For instence, cyano-bridged tetracyanonickelates 2À , [Ni(CN) 4 ] 2À , are suitable model compounds for structural and magnetic studies of such systems at low temperatures, because the tetracyanonickelate anion may bridge paramagnetic ions partially coordinated with amine ligands and thus to form molecular, 1D, 2D and 3D structures. Recently, 1D structures of [Cu(en) 2 Ni(CN) 4 ] (en ¼ ethylenediamine) [6][7][8], [Cu(dpt) Ni(CN) 4 ] (dpt ¼ dipropylenetriamine) [9], [Cu 2 (L) 2 Ni (CN) 4 ]Á2H 2 O (HL¼N -(3-hydroxypropyl)ethane-1,2-diamine) [10] and [Cu 2 (medpt) 2 Ni(CN) 4 ](ClO 4 ) 2 Á 2.5H 2 O (medpt¼bis(3-aminopropyl)methylamine) [11], 2D structures of [Cu(NH 3 ) 2 Ni(CN) 4 ] Á 2C 6 H 6 [12] and blue polymorph of [Cu(tn)Ni(CN) 4 ] (tn ¼ 1,3-diaminopropane) [13], and 3D structure of violet polymorph of [Cu(tn)Ni(CN) 4 ] [13] have been studied, respectively. The number of structural studies on molecular tetracyanonickelates (2-) [16,17].…”
