PublicationArticle 1, 3-Propanediamine, 1, 4-butanediamine (putrescine) and 1, 5-pentanediamine (cadaverine) complexes with zinc(ii), cadmium(ii) and mercury(ii) halides and pseudohalides(1975) I.S. Ahuja; Raghuvir SinghCoordination compounds formed by zinc(II), cadmium(II) and mercury(II) halides and pseudohalides with 1, 3-propane diamine, 1, 4-butanediamine (putrescine) and 1, 5-pentanediamine (cadaverine) have been prepared and characterized by molecular conductance and infrared spectral measurements down to 200 cm-1. Possible structures for these complexes in the solid state are discussed. © 1975, Taylor & Francis Group, LLC.

Ahuja; Raghuvir SinghComplexes formed by some zinc(II), cadmium(II) and mercury(II) salts with 2-, 3- and 4-cyanopyridines have been prepared and characterized by molecular conductance and infrared spectral measurements down to 200 cm-1. Possible structures for these complexes in the solid state are discussed. © 1974.PublicationArticle 4, 4'-Bipyridine complexes with some uranyl salts(1973) I.S. Ahuja; Rajindar SinghThe complexes formed by 4, 4'-bipyridine with uranyl chloride, sulphate, and nitrate of the type UO2(4, 4'-bipyridine)X2, where X = Cl or 1/2SO4, and UO2(4, 4'-bi-pyridine)1.5(NO3)2 have been prepared and their infrared spectra in the rock salt and low-frequency region (down to 200 cm-1) studied in the solid state. I.r. spectra of these complexes show that 4, 4'-bipyridine acts as a bidentate ligand bridging between two metal atoms. It is suggested that the sulphate and nitrate groups act as bidentate chelating ligands and the complexes are polymeric structures. © 1973, CSIRO.
