DEFINITION

Classification: 424/9.42

Transition, actinide or lanthanide metal containing:

(under subclass 9.4) Subject matter wherein the agent contains a transition, actinide, or lanthanide metal (Atomic Numbers 21-30, 39-48, 57-80, and 89-106, inclusive).

(1) Note. The metals included under transition, actinide, or lanthanide metals are Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu,

Zn, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Ac, Th, Pa, U, Np, Pu, Am, Cm, Bk, Cf, Es, Fm, Md, No, Lr, Unq, Unp, and Unh.

(2) Note. A complex of a metal and an organic compound is considered to be a compound per se and is classified based on the moiety (metal or organic compound) which occurs first in the classification schedule.

(3) Note. The transition, actinide or lanthanide metal may be complexed to a chelating agent.

(4) Note. An example of a compound provided for herein is: [figure]
