چکیده
U ranium tetraethoxy monobenzoate (1.251 g.) was taken in benzene (55 g .). To this tertiary butanol (0.65 g.) was added. The reaction m ixture was refluxed for seven hours. D uring this period benzene ethanol azeotrope was collected slowly. Followed by a few ml of pure benzene at 80 °C. On drying under reduced pressure as above a reddish brown viscous liquid (1.47 g.) sparingly soluble in benzene was ob tained.

Here, we report the synthesis of a Schiff-base mixed-ligand complex of cadmium(ІІ) in bulk and nano-scales via the precipitation and sonochemical methods, respectively. The complex formula is [Cd(3-bpdh)(3-bpdb)Cl2]n (1), where the ligands are 3-bpdh = 2,5-bis(3-pyridyl)-3,4-diaza-2,4-hexadiene and 3-bpdb = 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene. The structure of mixed-ligand complex (1) wa...
