A tetrahedrally coordinated cobalt(II) aminophosphonate containing one-dimensional channels

A tetrahedrally coordinated cobalt(II) phosphonate, Co(O3PCH2CH2NH2), has been synthesized using hydrothermal techniques. X-ray diffraction indicates that this material is a three-dimensional open framework with rings aligned along a single axis forming infinite one-dimensional channels. The framework decomposes just above 400 °C. Magnetic susceptibility data are consistent with weak antiferromagnetic ordering at low temperatures.
