PREPARATION AND CHARACTERIZATION OF [Ni (MAP) ] ; H- MAP = 2- (METHYLAMINO) PYRIDINE H. Aghabozorg* and H. H. Monfared

We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...

Dr W. H. Hylton

Dr William H. Hylton, formerly a general practitioner in Clevedon died suddenly on March 20th at the age of 83. William Hawkins Hylton?Bill, was born in Leeds in 1906. He was educated at Bridlington College. His father ran a building firm but died tragically of acute appendicitis when his son was aged 14. Bill intending to pursue the same career entered Leeds University and took a degree in eng...

CRYSTALLOGRAPHIC, MORPHOLOGICAL AND W-H MODELS INVESTIGATIONS ON Mn SUBSTITUTED ZnO NANOCRYSTALS

Mn doped ZnO nanocrystals were prepared by co-precipitation route sintered at 450 °C temperature. XRD results indicate that the samples having hexagonal (wurtzite) structure. From X-ray data it is found that the lattice parameters increase with increasing Mn concentration. The X-ray density decreases with increasing Mn concentration of Zn 1-x Mnx O nanocrystals. It indicates that the Mn...
