Single crystals of Tl 2 Zr(N[CH 2 COO] 3 ) 2 · 2H 2 O having optical quality and dimensions up to 30 × 25 × 12 mm have been grown from aqueous solutions by controlled lowering of temperature. The raw material was synthesized as the first fraction of crystallization during evaporation of an aqueous solution of (CH 3 NH 3 ) 2 Zr(N[CH 2 COO] 3 ) 2 · 2H 2 O and TlNH 2 SO 3 . A crystal structure analysis revealed an isotypy to the K 2 Zr(N[CH 2 COO] 3 ) 2 · 2H 2 O family, space group Ccc2 , a 1 = 14.780(2)Å, a 2 = 14.933(2)Å, a 3 = 8.901(1)Å, Z = 4, ρ calc. = 3.145 gcm ‐3 . Thermal stability, thermal expansion and pyroelectric, dielectric, piezoelectric, elastic and thermoelastic properties have been determined. All properties are closely related to those of Rb 2 Zr(N[CH 2 COO] 3 ) 2 · 2H 2 O.
