Abstract
The asymmetric unit of the title complex, [Zn(SCN)2(C6H6N2O)2], consists of one Zn(2+) cation located on a twofold rotation axis, as well as of one thio-cyanate anion and one neutral isonicotinamide ligand, both occupying general positions. The Zn(2+) cation is tetra-hedrally coordinated into a discrete complex by the N atoms of two symmetry-related thio-cyanate anions and by the pyridine N atoms of two isonicotinamide ligands. The complexes are linked by inter-molecular C-H⋯O and N-H⋯O, and weak inter-molecular N-H⋯S hydrogen-bonding inter-actions into a three-dimensional network.

Paramagnetic cations can be linked by small anionic ligands such as thiocyanate anions to enable a magnetic exchange between the cations (Palion-Gazda et al, 2015; Banerjee et al, 2005)
In this context we have reported on a number of coordination polymers with thiocyanato ligands that show different magnetic phenomena, including a slow relaxation of the magnetization which is indicative of singlechain magnetism (Werner et al, 2014; 2015a,b,c). In several cases, such phases can only be prepared by thermal decomposition of suitable precursor compounds (Näther et al, 2013), leading to microcrystalline powders for which a straightforward crystal structure determination is difficult
Summary
The synthesis of magnetic materials is still a major field in coordination chemistry (Liu et al, 2006) For their construction, paramagnetic cations can be linked by small anionic ligands such as thiocyanate anions to enable a magnetic exchange between the cations (Palion-Gazda et al, 2015; Banerjee et al, 2005). Paramagnetic cations can be linked by small anionic ligands such as thiocyanate anions to enable a magnetic exchange between the cations (Palion-Gazda et al, 2015; Banerjee et al, 2005) In this context we have reported on a number of coordination polymers with thiocyanato ligands that show different magnetic phenomena, including a slow relaxation of the magnetization which is indicative of singlechain magnetism (Werner et al, 2014; 2015a,b,c). The synthesis and crystal structure of the resulting compound, [Zn(NCS)2(C6H6N2O)2], are reported here
