Structural, spectroscopic and magnetic properties of thiocyanate complexes of Mn(II), Ni(II) and Cu(II) with the 1-methylimidazole ligand

Synthesis, crystal structures and properties of Ni(NCS)2-4-(hydroxymethyl)pyridine coordination compounds

“…In compound 2 the ethyl group of the ethanol molecule and in compound 4 one of the two 6-membered rings are disordered in two orientations and were refined using a split model. The crystal of 1 was racemically twinned and therefore, a twin refinement was performed (BASF parameter: 0.348 (16)). …”

Synthesis and Crystal Structure of N-(2-Pyridylmethyl)-L-Alanine) Isothiocyanate Cobalt(III)

“…In the IR spectrum of the Co(III) complex, a very strong infrared absorption band at 1609 cm −1 is attributed to υ C=C and υ C=N of the pyridyl ring, while the strong band at 2098 cm −1 suggest the presence of N=C=S stretch [14] [15] [16], as confirmed by the single crystal structure of the compound. Two distinct peaks at 362 nm and 497 nm are observed in the UV-Visible spectrum of the complex and attributed to spin allowed d-d transitions.…”

Synthesis, Structures and Properties of Cobalt Thiocyanate Coordination Compounds with 4-(hydroxymethyl)pyridine as Co-ligand

“…Compounds that consist of paramagnetic metal cations are of particular interest because they can show different magnetic properties and thus it is not surprising that an increasing number of new compounds were recently reported [5][6][7][8][9][10][11][12][13][14]. One group of these compounds are transition metal thiocyanato coordination polymers, which show a variety of different coordination modes including the terminal and the bridging coordination, with the latter being of special importance because cooperative magnetic properties can be expected [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. This is one reason why we are especially interested in thio-and selenocyanato coordination polymers, in which the metal centers are connected into chains by pairs of µ-1,3-bridging anionic ligands [35][36][37][38][39][40][41][42][43][44][45][46][47].…”
