Fig. 2 — Temperature-dependent unit-cell parameters of 1. a The dihedral angles between the Himd⁺ molecular planes and the crystallographic (010) face. As the temperature increases, both φ and θ gradually increase and finally reach 90° at 393 K. b The interlayer distances between CuCl₄²⁻ dianions separated by the Himd⁺ cations in layers A (d_A) and B (d_B). c The unit-cell length of 1. Upon heating, the b-axis length increases monotonically in the temperature range of 123 to 393 K, whereas the a-axis and c-axis lengths increase slightly from 123 to 263 K, and then decrease significantly from 273 to 393 K. d The anisotropic thermal expansion of the material along the principal axes (a′, b′, and c′) obtained from PASCal in the temperature range from 273 to 353 K
