Watson, William. H.2019-10-112019-10-1119801980https://repository.tcu.edu/handle/116099117/31771The synthesis and structures of four copper(II) dipivaloylmethane (DPM) complexes; Cu(DPM)(,2), Cu(,4)(OCH(,3))(,4)(DPM)(,4), Cu(,4)(O)(Pz)(,2)(DPM)(,4), and Cu(,9)(OHO)(OH)(,6)(DPM)(,9); are presented. The relationship between the structural geometry of these complexes and their magnetic behavior is also discussed. The Cu(DPM)(,2) complex is square planar. The Cu(,4)(OCH(,3))(,4)(DPM)(,4) structure is that of a step tetramer, while that of Cu(,4)(O)(Pz)(,2)(DPM)(,4) is a (mu)(,4)-oxo bridged complex with tetrahedral symmetry. The Cu(,9)(OHO)(OH)(,6)(DPM)(,9) structure has the overall geometry of a triangular prism. Reasons for the inconstant structural types for these and other known Cu(II)-DPM complexes are also examined. In addition, the synthesis and structure of tetrapyrazole copper(II) nitrate, Cu(Pz)(,2)(NO(,3))(,2), and (mu)(,4)-oxo-hexa-(mu)-bromo-tetrakis-{(3-quinulidione) copper(II)}, Cu(,4)(O)Br(,6)(3-quin)(,4) are presented. The structure of Cu(Pz)(,4)(NO(,3))(,2) is that of a distorted octahedron. The copper arrangement for Cu(,4)(O)Br(,6)(3-quin)(,4) is that of a regular tetrahedron.vii, 117 leaves, bound : illustrationsFormat: PrintengCopper--Magnetic propertiesCopper compoundsTextMain Stacks: AS38 .H61 (Regular Loan)Special Collections: AS38 .H61 (Non-Circulating)
