Bulk single crystals of zinc cadmium thiocyanate, ZnCd(SCN)(4) (ZCTC) with dimensions of 51 x 15 x 12 and 28 x 13 x 12 mm(3) have been obtained. Growth habits were investigated, two-dimensional nucleation growth mechanism and crystal twinning defect were observed from the as-grown crystals. The thermal diffusivities were measured, and then thermal conductivities were calculated with values decreasing from 1.3683 to 0.8739W.m (1) .K (1) and 0.8496 to 0.5356W. m (1) .K (1) as the temperature increasing from 303 to 423 K, along the a- and c-directions, respectively. The relative dielectric constants and elastic compliance constants at room temperature were determined. Meanwhile, first-principles calculation was used to calculate elastic constants.
