The metal complexes afforded the formulae: [Cu-2(TTAH)Cl-3(C2H5OH)(3)]0.5C(2)H(5)OH center dot H2O (1) , [Co-2(TTAH)(C5H5N)]Cl-2 center dot 2.5C(2)H(5)OH (2) , [Ni-2(TTAH)(C5H5N)(2)(OH)(2)(C2H5OH)(2)] (3) and [Zn-2(TTAH)(2))(OH)(4)(C5H5N)(2...
The average crystallite size (ACS) of the (Ba1ÀxLaxÞ Tið1Àx=4ÞO3 samples was calculated using Scherrer's formula22: D ¼ k à λ=β à cos θ; ð1Þ where D is the average crystallite size, k depends on the shape of crystallite size (k ¼ 0:9 for ...
