INTRODUCTION It is not only timely, for the reasons discussed below, to provide a survey of the use of magnetic susceptibility measurements for the study :of complex compounds, but also fitting that the subject should be discussed in a country whose scientists have made so many outstanding contributions to quantum mechanics in general and spectroscopy and magnetism in particular. I pay a specia...

Six Mn(II) coordination compounds with tetrazolate-5-carboxylate (tzc), have been synthesized and characterized. They are of the formula [Mn2(tzc)2(H2O)2].4H2O (), Mn(tzc)(H2O)2 (), [Mn2(tzc)2(phen)2(H2O)2] (), [Mn(tzc)(2,2'-bpy)(H2O)2] (), [Mn(tzc)(4,4'-bpy)] () and [Mn2(tzc)2(H2O)2].(bpp) (), where phen=1,10-phenanthroline, 2,2'-bpy=2,2'-bipyridyl, 4,4'-bpy=4,4'-bipyridyl, and bpp=1,3-di(4-py...

The coupling of tetrazotised 1,8-diaminonaphthalene with 1,3-dicarbonyl compounds [acetylacetone,methylacetoacetate and acetoacetanilide] yielded a new series of tetradentate ligand systems. Analytical, IR,1H NMR and mass spectral data indicate that the compounds exist in the intramolecularly hydrogen bondeddihydrazone form. Dibasic tetradentate N2O2 coordination of these compounds in their [ML...

An equimolar mixture of 3-formylsalicylic acid and furoic acid hydrazide, refluxed in MeOH, forms the Schiff base (I). The latter upon reacting with mercaptoacetic acid in dry benzene, undergoes cyclization and forms N-(2carbamoylfuranyl)-C-(3'-carboxy-2'-hydroxyphenyl)thiazolidin-4-one, LH3 (II). A MeOH solution of II reacts with Co(II), Ni(II), Zn(II), Fe(III) and MoO2(VI) ions and forms the ...
