Abstract: 

The compound Nd4Ti9O24 was prepared by heating mixtures of Nd2O3/TiO2 (1 : 4.5) at temperatures of T = 1 330-degrees-C in air (2 x 1 d). Single crystals of Nd4Ti9O24 were obtained by chemical transport reaction (T2 --> T1; T2 = 1000-degrees-C, T1 = 900-degrees-C, 14 d) using chlorine (p(Cl2, 298 K) = 1 atm) as transport agent with Nd4Ti9O24 as starting material.

Nd4Ti9O24 crystallizes in the orthorhombic space group Fddd (No. 70) with a = 13.9926(11) angstrom, b 35.2844(21) angstrom, c = 14.4676(17) angstrom (Z = 16). The structure was refined to give R = 4.0% and R(w) = 3.7%. Main building units are TiO6 octahedra, NdO6 distorted square antiprisms and NdO6 octahedra.
