Redetermination of the crystal structure of tetrammineplatinum(II) dichloride – A microporous hydrogen-bonded 3D network exhibiting a temperature-dependent order-disorder phase transition

The title compound [Pt(NH3)4]Cl2 (1), prepared by reaction of (NH4)2[PtCl4] with an excess of NH3 in aqueous solution, was crystallized from water and its structure redetermined by single-crystal X-ray diffraction at four different temperatures in the range from 273 K down to 100 K. 1 is composed of ...
