“…The ambidentate nature and the highly versatile bridging modes of the NCS − ligand allow the formation of a wide variety of polymeric metalthiocyanate structures. We found only one instance where thiocyanate groups are linked with a cadmium atom exceptionally via N atoms [18]. In 3 each cadmium atom is bonded exclusively to six hard N atoms of NCS − ions.…”

Three heterometallic Cu/Cd complexes [Cu(en) 2 CdBr 4 ]·dmso (1), [Cu(en) 2 CdI 4 ]·dmf (2) and [{Cu(en) 2 } 3 Cd(NCS) 6 ](NCS) 2 (3) have been synthesized by means of an open-air reaction of unactivated copper powder, cadmium oxide, NH 4 X (X = Br, I, NCS) and ethylenediamine in non-aqueous solvents, like dmso, dmf and CH 3 OH. The selection of a counter-anion in the initial ammonium salt provides a facile approach to the controlled assembly of one-or two-dimensional extended networks. Crystallographic investigations reveal that 1 and 2 possess 1D structures via semi-coordination (Cu 2+ ...X) and hydrogen bonds (NH 2 ... O Solv ) forming chains with a zigzag arrangement of copper and cadmium atoms. In complex 3 the cadmium atom of each Cd(NCS) 6 4− anionic block forms bridges with Cu(II) ions via the sulfur atoms of thiocyanate groups to give 2D polymeric sheets, featuring two different ring sizes, one a 32-membered ring [Cu 4 Cd 4 (µ−SCN−S, N) 8 ] and the other a 16-membered ring [Cu 2 Cd 2 (µ−SCN−S, N) 4 ]. It is noteworthy, that 3 shows a quite rare Cd(NCS) 6 4− fragment with N-bonded thiocyanate groups.

2004) Template self-assembly of cyano-bridged supramolecular complexes {[Cu(en) 2 ][KM(CN) 6 ]} n (M = Cr III , Fe III , Co Reaction of K 3 [M(CN) 6 ] (M ¼ Cr III , Fe III , Co III ) with [Cu(en) 2 ](ClO 4 ) 2 in water gives three cyanide-bridged supramolecular complexes, {[Cu(en) 2 ][KM(CN) 6 ]} n [M ¼ Cr III (1), Fe III (2), Co III (3); en ¼ ethylenediamine], which have been characterized by elemental analysis, ICP analysis, IR spectra, TGA-DTA analysis and X-ray diffraction. Complex 1 crystallizes in the monoclinic, space group C2/c with cell dimensions a ¼ 0.85237(12), b ¼ 1.7014(3), c ¼ 1.2103(2) nm, ¼ 98.70(2) and Z ¼ 4, and 2 crystallizes in the same space group with a ¼ 0.8401(2), b ¼ 1.6844(5) Å , c ¼ 1.1859(2) nm, ¼ 98.98(2) and Z ¼ 4. The crystal structures of 1 and 2 reveal a novel three-dimensional porous framework in which [Cu(en) 2 ] 2þ acts as a template, [M(CN) 6 ] 3À as a building block and K þ as a connecting unit.
