Chapter 7 7.4 Name and draw structures of the following complexes? (a) [Ni(CO) 4 ]? The name of this complex is tetracarbony1nickel(0). Its structure is tetrahedral. (b) [Ni(CN) 4 ] 2- ? The name of this complex is tetracyanonickelate(2-). Note the use of the suffix - nickelate instead of -nickel, since the complex is negatively charged. The structure is square- planar. (c) [COCl 4 ] 2- ? The name of this complex is tetrachlorocobaltate(2-). Its structure is tetrahedral. (d) [Ni(NH 3 ) 6 ] 2+ ? The name of this six-coordinate octahedral complex is hexaamminenicke1(2+). 7.7 Draw structures? a) Pentaamminechlorocobalt(lII) chloride? (b) Hexaaquairon(lII) nitrate? (c) cis-dichlorobis(ethylenediamine)ruthenium(II)?

(d) m -Hydroxobis(pentaamminechromium(III)) chloride? 7.8 Name and draw structures? (a) cis -[CrCl 2 (NH 3 ) 4 ] + ? This complex contains (i) two Cl- ligands = dichloro, (ii) four NH 3 ligands = tetraammine (not tetraamine or tetrammine), and (iii) Cr 3+ in a complex that is not an anion = chromium(III). Putting (i), (ii), and (iii) together, the name of this complex is cis-
