A member of the series M(I)M(III)(ND3)6(ClO4)2X2, CsC0(ND3)6(ClO4)2Cl2, has been examined by single crystal time-of-flight neutron diffraction at 20, T(c)-10, T(c)+10, and 290 K, adding to previous X-ray diffraction studies of some compounds in this series. T(c) is the phase transition temperature of 250(1) K observed by DSC between closely related simple trigonal structures - twinned ordered R3 and disordered R3m, both with Z= 3 and the former with a =7.210(2) Å, c = 26.819 Å at 20K. The twin...[Show more]
