Synthesis and structural characterization of two cobalt phosphites: 1-D (H{sub 3}NC{sub 6}H{sub 4}NH{sub 3})Co(HPO{sub 3}){sub 2} and 2-D (NH{sub 4}){sub 2}Co{sub 2}(HPo{sub 3}){sub 3}

Two new cobalt phosphites, (H{sub 3}NC{sub 6}H{sub 4}NH{sub 3})Co(HPO{sub 3}){sub 2} (1) and (NH{sub 4}){sub 2}Co{sub 2}(HPO{sub 3}){sub 3} (2), have been synthesized and characterized by single-crystal X-ray diffraction. All the cobalt atoms of 1 are in tetrahedral CoO{sub 4} coordination. The structure of 1 comprises twisted square chains of four-rings, which contain alternating vertex-shared CoO{sub 4} tetrahedra and HPO{sub 3} groups. These chains are interlinked with trans-1,4-diaminocyclohexane cations by hydrogen bonds. The 2-D structure of 2 comprises anionic complex sheets with ammonium cations present between them. An anionic complex sheet contains three-deck phosphite units, which are interconnected by Co{sub 2}O{sub 9} to form complex layers. Magnetic susceptibility measurements of 1 and 2 showed that they have a weak antiferromagnetic interaction. - Graphical abstract: The 2-D structure of (NH{sub 4}){sub 2}Co{sub 2}(HPO{sub 3}){sub 3} comprises anionic complex sheets with ammonium cations present between them. An anionic complex sheet contains three-deck phosphite units, which are interconnected by dimmeric Co{sub 2}O{sub 9} to form complex layers.
