a) Give the correct IUPAC name and sketch the structure of the transition metal

Question

a) Give the correct IUPAC name and sketch the structure of the transition metal complex for each of the following compounds. If multiple stereoisomers are possible, give both names and structures:

1) [Pt(NH3)2Cl2]
2) [Cr(NMe3)4Br2]PF6
3) K[Co(edta)], where H4(edta) = ethylenediaminetetraacetic acid 4) [Ir(CO)Cl(PPh3)2]
5) Hg[Co(NCO)4]
6) [Fe(acac)3], where H(acac) = acetylacetone
7) [Co(NH3)6]3+[Cr(CN)6]3-
8) [{Co(NH3)5}2(-OH)]Cl5
9) [TiCl3(thf)3], where thf = tetrahydrofuran
10) [Ru(bpy)2Cl2], where bpy = 2,2’-bipyridine
11) V(O)(acac)2, where H(acac) = acetylacetone

b) Determine the oxidation state and dn electron count for all complexes.

Explanation / Answer

1) [Pt(NH3)2Cl2]     di chloro diamine platinum(II)
2) [Cr(NMe3)4Br2]PF6    dibromo tetrakiss trimethyl amine chromium(II) hexa fluoro phosporous
3) K[Co(edta)], where H4(edta) = ethylenediaminetetraacetic acid ptassium ethylenediaminetetracetic acid cobaltate (I)

4) [Ir(CO)Cl(PPh3)2] cabonyl chloro bis( triphenyl phosphino iridium(I))

5) Hg[Co(NCO)4]   cobalt mercury thiocyanate
6) [Fe(acac)3], where H(acac) = acetylacetone    tri acetylacetone iron (III)
