A new layer-structured Co(NH3)(HPO4).1/2H2O has been prepared hydrothermally in the presence of Co(sen)Cl3, AlCl3.6H2O, phosphoric acid, and ammonium hydroxide. The structure of this material has been characterized by single-crystal X-ray diffraction analysis. Cobalt metal ion leading to layer-structured framework consists of polyoctahedra CoO5N and one ammonia molecule is coordinated on the axial site of cobalt (II) as organic ligand. The distance of interlayer is 5.17Å and it is occupied with only water molecule interacting with –OH group of phosphorous by hydrogen bonding. |
