- 5) Consider the rhodium complex below. Reaction with 1 equivalent of oxygen gas oxidizes the metal centre and gives a new complex with cis, distorted octahedral geometry. Draw the structure of the product and give the oxidation state, valence electron count, and d-electron count for both rhodium complexes. Ar 1 eq. O2 Ph3P. Rh Ph3P -"Bu ?arrow_forward1. The Cp2Rh2[u-(CF3C=CCF3)](CO)(CNR) complex has a Rh-Rh bond distance of 2.67 Å, strongly indicating a covalent bond between the rhodium atoms. How would you electron count this complex to accommodate a Rh-Rh covalent bond? Clearly show the electron counting.arrow_forwardA transition metal, M, is coordinated in an octahedral fashion to the following ligands: Two chloro ligands; One (2-aminoethyl)phosphine ligand with the following structure abbreviation: N P One (0-CHz-CHz–SJ²-ligand with the following structure abbreviation: S a) Sketch all possible isomers, clearly indicating pairs of enantiomers b) Classify the configuration of chiral isomers as A or Aarrow_forward

Explain why in details? (ii) The bond distance and angle in SO2Cl2 and S2Cl2 and how many lone pairs are in ICL4-??arrow_forwardHow many bonds could each of the following chelating ligands form with a metal ion?

The o donor orbital is anti- bonding with respect to the C-N bond. Given that the v(CN) stretching frequency in the IR spectrum of [Pt(CN)4]² is 2170 cm¹ while free CN-exhibits v(CN) at 2080 cm¹¹, which property, o donation or acceptance dominates in this complex?

BIU O A 2 !!!arrow_forwardCis-diamminedichloroplatinum (II) or “cisplatin” is a square planar complex with the formula [Pt(NH3)2Cl2]. Cisplatin is an anticancer drug that works by bonding to two adjacent guanine bases on the same strand of DNA, creating a kink which disrupts DNA replication. Each bond to a guanine base is formed by displacing one Cl ligand on cisplatin. The closely related complex trans-diamminedichloroplatinum (II) is completely ineffective as an anticancer agent.
