      Castañeda Magliona, Fernando; Terraza, C. A.; Bunton, Clifford A.; Gillitt, N. D.; Garland, María Teresa (TAYLOR & FRANCIS LTD, 2003-09)
      The stabilized phosphorus ylides, Ph3P=C(CO.R')CO.OR, 1, R=Et, R' =CH2P+Ph3; 2, R=R'=Me; 3, R=Et, R'=Me; 4, R=Pr-i; R'=Me, 5, R=Bu-t; R'=Me, adopt a near planar conformation in the crystal which allows extensive electronic ...
    • Sucrose bis(1,10-phenanthroline) cobalt(III). Comparison of semi-empirical and ab initio geometrical optimizations 
      Parada Aliste, José; Ibarra, Carmen; Gillitt, N. D.; Bunton, Clifford A. (PERGAMON-ELSEVIER SCIENCE LTD, 2005-06-28)
      The title compound (sucrose Co(phen)(2)) is a dication with the Delta-configuration at Co(III) and ligation through O-2(g) and OH-1(f). Earlier geometrical optimization with semi-empirical PM3(tm) parameters had fitted ...
