X-Ray crystal structures are reported for six transition metal complexes of the ligands 1,2-bis(8-quinolyloxymethyl)benzene (3) and 1,3-bis(8-quinolyloxymethyl)benzene (4). In three mononuclear copper(II) and cobalt(II) complexes ligand 3 acts as a chelating ligand, with either N,O,N’-tridentate or N,O,O’,N’-tetradentate coordination. A novel binuclear silver(I) complex of 3 is shown to... [Journal Article]

The X-ray absorption spectra of the reference and model compounds HgCl2, PhHgCl, PhHgOAc and [(PhHg)2OH][BF4].H2O have been analysed in both the XANES and EXAFS regions, and the technique was extended to determine the structures of (PhHg)2O, PhHgOH, and the basic salts PhHgOH.PhHgNO3 and PhHgOH.(PhHg)2SO4, which were previously structurally uncharacterised. Results indicate that (PhHg)2O is a...This is an authors version of an article published in the, Journal of the Chemical Society, Dalton Transactions, (c) The Royal Society of Chemistry 2000, at the Dalton Transactions webpage.

X-ray crystal structures are reported for five silver(I) complexes of four monoterpenoid alkenes. Discrete mononuclear complexes of the chiral alkenes (1S)-(-)-α-pinene and (1S)-(-)-ß-pinene with silver perchlorate and silver hexafluorophosphate are described. The achiral diene γ-terpinene forms a discrete mononuclear adduct with silver hexafluorophosphate and a two-dimensional polymeric... [Journal Article]

The crystal structure of bis-(pyridoxylidene-L-valine)nickel(II) hydrate (referred to as nickel(II) pyridoxylidene L-valine) has been determined but the difficulty in detecting small deviations from body-centred symmetry, and in locating all solvent molecules, has precluded an accurate analysis. Octahedral coordination to the nickel atom is achieved by the attachment of two Schiff base units.... [Thesis or Dissertation]

Restricted Item. Print thesis available in the University of Auckland Library or available through Inter-Library Loan. This thesis describes the X-ray structural analyses of a selection of non-enzymatic Vitamin B model systems with a view to examining structures and possible electronic shifts in complexed intermediates. The compound (3-methoxysalicylidene-DL-valinato)aquacopper(II), in which... [Thesis or Dissertation]

Restricted Item. Print thesis available in the University of Auckland Library or available through Inter-Library Loan. Essentially this thesis presents the X-ray crystallographic results of eleven crystal structures, comprised of seven low valence gold, one amido (NHR) transition metal and three imido (NR) transition metal complexes. The first section of the thesis deals with the gold... [Thesis or Dissertation]

This thesis describes the single crystal x-ray analyses of six novel organometallic osmium complexes and three complexes of the tridentate dentate ligand 1,6-bis(diphenylphosphino)-trans-hex-3-ene with the transition metals iridium, rhodium and ruthenium. The complexes of carbon monosulphide and carbon monotelluride with osmium, OsCl2(CO)(CS)(PPh3)2 and OsCl2(CO)(CTe)(PPh3)2, exhibit linear... [Thesis or Dissertation]

There has been considerable interest during recent years in both naturally-occurring and synthetic oxygen-carrying compounds. Those which do occur naturally include haemoglobin from red blood cells in which the oxygen carrying molecule contains the haem group, haemocyanin from the ‘blue blood” of lobsters and crabs, which is a copper-containing compound, and the violet hemerythrin, a...
