One- and three-dimensional octacyanometalate(IV) networks constructed via a building block approach: {[trans-NiII(tn)2(OH2)][trans-NiII(μ-NC)2(tn)2][(μ-NC)3MIV(CN)5]·6H2O} (MIV=Mo, W) and Cs4[CuII(OH2)4]2[CuII(NH3)]4[MoIV(CN)8]4·2H2O

Synthesis, crystal structure and magnetic properties of a three-dimensional cyano-bridged heterometallic complex {NiII(Me6-[14]ane-N4)}2[WIV(CN)8]·6H2O

“…Among them, the bimetallic assemblies built by Mn(II, III), Cu(II) and Co(III) complexes with octacyanometalate anions have been surveyed extensively [1][2][3]. However, just a few bimetallic assemblies based on Ni(II) and M(IV, V) (M = Mo, W and Nb) building blocks have been investigated, including isolated clusters [4][5][6], one-dimensional [7,8] and two-dimensional [4,7] structures. Although the preparations, infrared and magnetic studies of the compounds M II 2 ½Mo IV ðCNÞ 8 Á nH 2 OðM II ¼ Zn; Cu; Ni; Co; Fe; Mn; n = 2-9) [9] 8 ] 4À (M = Mo, W) generally exhibit sharp, very intense bands in the region 2070-2130 cm À1 , while bridged cyano ligands shift to higher frequencies [2].…”

Therefore, a very strong band at 2111 cm À1 is reasonably assigned to the terminal cyano stretching vibration.…”

Chromium, molybdenum and tungsten

“…143 It was reported that molybdenum and tungsten dialkylhydrazido complexes [M(dppe) 2 (NNC 5 H 10 )] 21 (M ¼ Mo, W; compounds A Mo and A W ) and their two-electron-reduced counterparts [M(dppe) 2 (NNC 5 H 10 )] (compounds B Mo and B W ) were characterised structurally and spectroscopically. 144 It was also reported that treatment of [Ni II (tn) 3 ][OTs] 2 or aqueous solutions containing nickel(II) p-toluenesulfonate and tn with aqueous K 145 An additional three-dimensional network, Cs 4 [Cu II (OH 2 ) 4 ] 2 [Cu II (NH 3 )] 4 [Mo IV (CN) 8 ] 4 Á 2H 2 O was also reported. 145 Influence of axial ligands, MeCN, H 2 O, py, and pip, on distortion of (2,3,5,10,12,13,15,20-octaphenylporphinato)chromium(III), [Cr(OPP)] 1 , was investigated by X-ray crystallography and UV/Vis and ESR spectroscopies.…”

Measurement and Correlation of the Solubility of Hexaquonickel(II) Bis(p-toluenesulfonate) in Water + Ethanol Solvents within 288.15–333.15 K

“…Ni­(OTs) 2 ·6H 2 O can be used as the raw material in the synthesis of [(dppe)­(CO)­Fe­(S 2 C 3 H 6 )­(μ-H)­Ni­(dppe)]­BF 4 ([2H]­BF 4 ) to study the [NiFe]­hydrogenase active site . It is also of great importance in the synthesis and characterization of one- and two-dimensional octacyanometalate­(V) networks or one- and three-dimensional octacyanometalate­(IV) networks, which can be used to construct clusters and extend arrays of metal centers linked via cyanides. Furthermore, Ni­(OTs) 2 ·6H 2 O is useful in the preparation of 2,6-bis­(hydroxymethyl)­pyridine, which can act as a chelating ligand in coordination compounds …”
