The X-ray diffractgram of a representative metal complex
of Pr(III) was scanned in the range 5-100° at wavelength 1.54
Å (Fig. 2). The diffractogram and associated data depict 2θ
values for each peak, relative intensity and inter planar spacing
(d-values). The diffractogram of Pr(III) complex showed ten
reflections with maxima at 2θ (22.99709) corresponding to d
value 1.97167 Å. The X-ray diffraction pattern of the complex
with respect to major peaks having relative intensity greater
than 10 % have been indexed by using computer programme36.
The above indexing method also yields miller indices (hkl),
unit cell parameters and volume. The unit cell of Pr(III)
complex yielded values of lattice constants, a = 23.77998 Å,
b = 4.62100 Å, c = 3.56444 Å and unit cell volume, V = 165.39
(Å)3. In concurrence with these cell parameters of Pr(III) complex,
the condition such as a ≠ b ≠ c and α = β = γ = 90° required for
the compounds to be orthorhombic were tested and found to be
satisfactory. The above values indicate that the metal complex
has orthorhombic crystal system.
