| Contents: |
Two isomorphous one-dimensional chain complexes Co(NCS)2(Him)2 (1) and Mn(NCS)2(Him)2 (2) (Him = imidazole) have been prepared and characterized structurally. Both 1 and 2 crystallize in the monoclinic system, space group P21/n, and the structures consist of one-dimensional polymeric chains in which metal ions are bridged by two thiocyanate groups bonding in end-to-end fashion. Both 1 and 2 exhibit two-dimensional sheet structures with N-H ··· S hydrogen bonds and three-dimensional supramolecular network structure with π ··· π stacking interactions. IR spectra indicate the presence of bridging thiocyanate groups in both 1 and 2, confirmed by their structures. The variable temperature magnetic susceptibility, measured in the 2-300 K range, indicates weak antiferromagnetic exchange interactions in complex 2. |
