draw these 3 structures perfectly please. I added directions but they may not be correct so please check for sure. 1. Dichlorotris (triphenylphosphine)ruthenium( lI) [RuClz(PPh3)a]: This complex features a ruthenium center coordinated by two chloride ions and three triphenylphosphine ligands. The structure is often described as a distorted square pyramid, with the three phosphine ligands and two chloride ions creating the coordination environment around the ruthenium atom. 2. Dichlorobis(triphenylphosphine) (3-phenylinden-1-ylidene)ruthenium(ll) [RuCl2(PPha)2(carbene)]: In this complex, the ruthenium center is coordinated by two chloride ions, two triphenylphosphine ligands, and a carbene ligand derived from 1,1-diphenyl-2-propyn-1-ol. The carbene ligand forms a double bond with the ruthenium, replacing one of the triphenylphosphine ligands compared to the previous complex 3. Dichlorobis (tricyclohexylphosphine) (3-phenylinden-1-ylidene)ruthenium(ll) [RuCl2(PCy3)2(carbene)]: Known as the first-generation Grubbs catalyst, this complex has a ruthenium center coordinated by two chloride ions, two tricyclohexylphosphine ligands, and a carbene ligand. The bulky tricyclohexylphosphine ligands enhance the catalyst's activity and stability in olefin metathesis reactions.
