Abstract
The transition metal squarates M(C4O4) · 4 H2O (M2+ = Mn2+, Fe2+, Co2+. Ni2+, and Zn2+) are isotypic. They crystallize monoclinically, space group Ce-Cf, and consist of one-dimensional chain molecules [xxx] with the chain axes alternatively in direction [110] and [110]. The transition metal is octahedrally coordinated by two oxygen atoms of two C4O4 2- -anions in rrarcs-position and 4 water molecules. Neighbouring chains are interlinked by hydrogen bonds. The distance between the planes of the parallel C4-rings of neighbouring chains is similar to the layer distance in graphite.Keywords
