Claim 19:
20. The method of claim 19,
wherein the ligands are represented by the chemical formula:

(Y—)k-n—(X)-(-L)n 

wherein k is 2, 3 or 5, and n is 1, 2, 3, 4 or 5 such that k-n is not less than zero;
X is O, S, S═O, SO2, Se, Se═O, N, N═O, P, P═O, As, or As═O;
each of Y and L, independently, is aryl, heteroaryl, or a straight or branched C2-12 hydrocarbon chain optionally containing at least one double bond, at least one triple bond, or at least one double bond and one triple bond,
wherein the hydrocarbon chain can be optionally substituted with one or more C1-4 alkyl, C2-4 alkenyl, C2-4 alkynyl, C1-4 alkoxy, hydroxyl, halo, amino, nitro, cyano, C3-5 cycloalkyl, 3-5 membered heterocycloalkyl, aryl, heteroaryl, C1-4 alkylcarbonyloxy, C1-4 alkyloxycarbonyl, C1-4 alkylcarbonyl, or formyl, and wherein the hydrocarbon chain can also be optionally interrupted by —O—, —S—, —N(R,)—, —N(Ra)-C(O)—O—, —O—C(O)—N(Ra)-, —N(R,,)—C(O)—N(Rb)-, —O—C(O)—O—, —P(Ra)—, or —P(O)(Ra)-, and
wherein each of Ra and Rb, independently, is hydrogen, alkyl, alkenyl, alkynyl, alkoxy, hydroxylalkyl, hydroxyl, or haloalkyl.
