The present invention relates to new nitrogen-containing organophosphorus compounds having chloro- or bromoalkyloxy substituents bonded to phosphorus in ester structures. ##STR1## R is haloalkyl of 2 to 5 carbon atoms, and R' is alkyl or alkenyl of 1 to 15 carbon atoms. The phosphorus compounds have utility as fire retardants and as biologically active materials.
