Abstract

The crystal and mol. structure of the title compound was determine The crystals are orthorhombic with space group Pna21; a 1.524(1), b 0.922(1), c 1.611(1), d.(obsd.) = 1.79 and d.(calcd.) = 1.83 for Z = 4. The structure was solved by heavy atom method and refined by least squares to R = 0.0333 and Rw = 0.0282 for 2136 reflections. A structure is a distorted antiprism with 2 Cl- and 6 urea coordinated to La. The core packing model was used to explain its mol. structure.

Key words: CHLORIDE, MOLECULAR STRUCTURE, UREA, ACCUMULATION, STRUCTURAL ANALYSIS, LANTHANUM COMPLEX

CLC Number:
