Abstract
Abstract Hexacoordinated transition metal compounds, useful as antiknocks, having the structure ##STR1## wherein M is a divalent metal selected from the group Mn, Fe, Co and Ni, L 1 and L 2 are the same or different chelate-forming β-diketone groups having from 5 to 20 carbon atoms, one or both of L 1 and L 2 having at least one polyfluoroalkyl group, --CF 2 X, adjacent to the carbonyl group, X is selected from the group H, F, Cl, phenyl, C 1 -C 6 alkyl and C n F 2n Y, n is 1 to 6, Y is H, F, or Cl, L 3 is a ligand having the structure A-Z-B, wherein A and B are the same or different members of the group --NH 2 , --NHR 5 , --NR 5 R 6 , OH, OR 5 , SH, SR 5 and PR 5 R 6 , R 5 and R 6 are the same or different members of the group C 1 to C 4 alkyl, and Z is a divalent hydrocarbyl group having 2 to 10 carbon atoms selected from a member of the group alkylene, phenylene and cycloalkylene, each member providing 2 or 3 carbon atoms between A and B, with the proviso that when Z is phenylene, the number of carbon atoms between A and B is 2.
