Temperature dependence of the (a) unit-cell volume, (b) β angle and (c) unit-cell parameters for ETYFUM sample crystal A (solid and dotted lines) and ETYSUC I sample crystal A (dashed lines). The lower subscripts EF, EF-lt and ES-I stand for ETYFUM, ETYFUM low temperature and ETYSUC Phase I, respectively. The insets in (a) show indicatrix plots representing thermal expansion tensors (PTE and NTE marked in red and blue, respectively) calculated using PASCal (Cliffe & Goodwin, 2012
