Question

for the following compounds:

i) give the correct name and indicate the possible isomers for parts (d, f, g,h,j)

ii) determine the dⁿ configuration, coordination number for the metal and electron count according to the 18 electron rule

iii) calculate the spin only magnetic moment

a) K [Mn(CO)_5]   b) H[AuCl₄]

c) Na[n²-C₂H₄)PtCl₃] d) [(n⁶-C₆H₆)₂Cr]

e) K₂[PdCl₄] f) [Ru(H)(Cl)(CO)(PPh₃)₃]

g) [Co(NO₂)(NH₃)₅]SO₄ h) [CoCl(en)(NH₃)₃]Cl

i) [Ir(phen)(Cl)₄] j) [Cr(en)₃]Cl₃

Answer 1

d) Nine types of isomers are present in dibenzenechromiumtricarbonyl . The heating fully acetylated or methylated aryl O-, S-, N- and C-glycosides of D-glucopyranose and D-mannopyranose with hexacarbonylchromium. All tricarbonylchromium complexes were fully characterized. The structures of nine crystalline complexes.

f)In the study of RuHCl(CO)(PPh3)(L-L') systems have so farpointed out the existence of such optical isomers. From thebasis of optical isomerism and the relationship between coupling constant and ligand geometry of hydrido phosphine metal complexes,11 the RuHCl(CO)(PPh3)(s,s-chiraphos) complex seem to have four distinct isomers in solution due to a chiral bidentate ligand making two enantiomers and two diastereomers possible.

h) there only three isomeres present .

g)

III) spin magenetic moment

h)  [CoCl(NH₃)₅] Cl₂
