3 . The molecular Mn(II) complex is disordered and the chargebalancing thiocyanate are disordered, with the site bound to the framework occupied by water and thiocyanate in a 0.53:0.47 ratio, and the site bonded to the molecular Mn(II) complex showing the reverse. When the temperature of the crystal was raised to 300 K this ratio was found to be instead 0.7:0.3, indicating that a higher proportion of the NCS ligands are now bound to the framework, which suggests that there may be dynamic effects. The presence of disorder means that it was not possible to determine the relative proportions the Mn(H 2 O) 5 (NCS) + Mn(H 2 O) or Mn(H 2 O) 4 (NCS) 2 complexes. [Fig. .
