Synthesis, Crystal Growth, Structural and Physical Properties of bis(thallium) bis(nitrilotriacetato) zirconate dihydrate, Tl2Zr(N[CH2COO]3)22H2O

Single crystals of Tl2Zr(N[CH2COO]3)22H2O having optical quality and dimensions up to 30 x 25 x 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 (CH3NH3)2Zr(N[CH2COO]3)2 2H2O and TlNH2SO3. A crystal structure analysis revealed an isotypy to the K2Zr(N[CH2COO]3)2 2H2O family, space group Ccc2, a1 = 14.780(2)Å, a2 = 14.933(2)Å, a3 = 8.901(1)Å, Z = 4, rhocalc. = 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 Rb2Zr(N[CH2COO]3)2 2H2O.

Keywords: Tl2Zr(N[CH2COO]3)2 2H2O, synthesis, piezoelectricity, elasticity, thermoelasticity
