The IUPAC definition of a transition element is that it is an element that has an incomplete d-subshell in either the neutral atom or its ion. Thus the group 12 elements are member of the d-block but are not transition elements. Chemically solft members of the d-block occurs as sulphide minerals and are partially oxidised to obtain the metal, the more electropositive 'hard' metals occurs as oxides and are extracted by reduction. Opposite to p-block elements, the higher oxidation states are favoured by the heavier elements of d-block Metals on the right of the d-block tend to exist in low oxidation states and form complexes with the ligands. Square-planar complexes are common for the platinum metals and gold in oxidation states that yield d^8 electronic configuration, which include RH(I),Ir(I),Pd(II),Pt(II) and Au(III). The most distinctive features/properties of transition metal complex is their wide range of colours.The crystal field theory attributes the colour of the coordination compounds to d-d transition of the electron.It is important to note that (a) in absence of ligand, crystal field spilling does not occur and hence the substances is colourless, (b) the type of ligand also influences the colour of the complexes. Which of the following has dsp^2 hybridisation and is diamagnetic in nature ? (i) Na_4[Cr(CO)_4] , (ii) [Ni(DMGH)_2] , (iii) [PtHBr(PEt_3)_2] (iv) [As(SCN)_4]^(3-) , (v) [AuBr_4]^(-)
coordination compounds often show various types of isomerism. The isomerism can be categorized in two main types (a) structural isomerism (b) stereo or space isomerism Structural isomerism arises due to the difference in structures of coordination-sempounds while stereo or space isomerism arises on account of the different positions and arrangements of ligands (atoms or groups) in space around the metal lonStructural isomerism can be classified in following types (i) tonization isomers- which give different ions in solution, e.g. [CoBr(NH_(3))_(5)]]SO_(4) and [Co(SO_(4))_(5)(NH_(3))_(5)]Br Hydrate isomers which differ in H_(2)O as ligand or as hydration, e.g. [Cr(H_(2)O)_(5)]CI_(2)(H_(2)O)]Cl_(2).H_(2)O[CrCl_(2)(H_(2)O)]CI.2H_(2)O (iii) Linkage isomers, which differ in atom linked to 'metal atom, e.g. [CO(NO_(2))(NH_(3))_(5)]^(2+) and CO(ONO)(NH_(3))_(6)]^(2+) Coordination isomers- which involve interchange of ligands, e.g. [Co(NH_(3))_(6)] [Cr(CN)_(6)] and [Cr(NH_(3))_(6)] [Co(CN)_(6)] (v) Coordination position isomerism-which arises in the bridged complexes due to the difference in the attachment of ligands with the metal atoms QThe total number of possible isomers for the complex compound [Cu^(ll)(NH_(3))_(4)] [Pt^(ll)Cl_(4) ]are
