“…Although the CN stretching frequencies for Nbonded thiocyanate complexes occur in a lower region (2050 cm À1 ) than those observed for the S-bonded complexes (2100 cm À1 ) [19,20], the electronic and steric effects caused by the dppb and Me-bipy ligands strongly affects the mCN frequency. The bands corresponding to m(CS) stretching and d(NCS) deformation are found at 760 cm À1 and 470 cm À1 , respectively.…”

“…Particularly relevant to the present work is that nickel(II) thiocyanate complexes have the details of their crystal architectures controlled by relatively weak forces such as hydrogen bonding (Ðaković et al, 2008) orstacking interactions. These aspects are evident in the crystal structures of nickel(II) isothiocyanate complexes with pyridine, -picoline and nico-tinic acid (Ðaković et al, 2008, 2011Wang et al, 2006;Saber et al, 2012;Goher et al, 2003).…”

Three nickel(II) isothiocyanato complexes of the formula trans-[NiL4(NCS)2] (L = ethylisonicotinate, methylisonicotinate and 4-benzoylpyridine) have been prepared: [Ni(ethylisonicotinate)4(NCS)2] (I), [Ni(methylisonicotinate)4(NCS)2] (II) and [Ni(4-benzoylpyridine)4(NCS)2] (III). All three complexes are monomeric and have a distorted octahedral geometry around Ni(II). Despite their apparent molecular similarity, the crystal density of (III) (1.454 g cm(-3)) is significantly higher than that of (I) and (II) (both 1.408 g cm(-3)), suggesting that the molecular packing is most efficient in (III). A study of the molecular Hirshfeld surfaces, together with density functional theory (DFT) calculations, provide insights into the origin of the molecular packing features, and it is suggested that the greater crystal density of (III) results from smaller intermolecular electrostatic repulsions.

Reaction of Co(NCS) 2 with 4-dimethylaminopyridine (DMAP) leads to the formation of four new compounds. The crystal structures of Co(NCS) 2 (DMAP) 2 (H 2 O) 2 ·2H 2 O (1), Co(NCS) 2 (DMAP) 2 (MeOH) 2 (2) and Co(NCS) 2 (DMAP) 2 (MeCN) 2 (3) consist of discrete simple solvato complexes in which the Co cations are octahedrally coordinated by two terminally Nbonded thiocyanate anions, two DMAP ligands as well as two solvato ligands. Co(NCS) 2 (DMAP) 2 (4/II) also forms discrete complexes, but the Co cations are tetrahedral coordinated by two anionic ligands and two DMAP ligands. Upon heating, the hydrate 1 transforms into 4/II, whereas the methanol solvate 2 transforms into a new polymorphic modification of [a]
