- A complex ion is formed from one Fe*, four Ct ions and two water motecuies. What is the structural formuta and name of the complex? show that it is diamagnetic by using valence bond theory. Construct the molecular orbital diagram. Include all the appropriate symmetry labels for all orbitals.arrow_forwardAccording to valence bond theory, what set of orbitals isused by a Period 4 metal ion in forming (a) a square planarcomplex; (b) a tetrahedral complex?arrow_forwardAn octahedral complex, MA,B,C2 (A, B, C are all monodentate ligands), has a total of 6 stereoisomers. Considering the point groups for each of these isomers, it can be concluded that none of these isomers has the following point group. C2v C1 D2h Which cation is mostly likely to form a complex with SCN' b Csarrow_forward
- An octahedral complex, MA4B2 (A and B are monodentate ligands), has two stereoisomers (trans and cis). Considering the point groups for each of these isomers, which of the following statements is correct? O The cis isomer is polar and the trans isomer is non-polar O The trans isomer is polar and the cis isomer is non-polar Both isomers are polar O Both isomers are non-polararrow_forwardDraw the electron first excited state electronic diagram of a weak field d7 octahedral complex.Indicate the term symbols of both ground state and excited state.arrow_forwardOne of the more striking hydride complexes is [ReH9]2-, which has tricapped trigonal prismatic geometry. Construct a representation using the hydrogen orbitals as a basis. Reduce this to its component irreducible representations, and indicate which orbitals of Re are of suitable symmetry to interact with the hydrogen orbitals.arrow_forward
- Draw the full molecular orbital diagram for [Fe(H2O)6] + 2. Each MO must have a drawing of the interaction and the appropriate Mulliken symbol. Approximate ligands down to their lone pairs, and derive the point group from only the geometry created by those donating atoms.arrow_forwardFor the complex [Cr(OH2)6]2+ i) Give the ground state free atom term symbol. ii) State whether it is paramagnetic or diamagnetic. iii) Give the spin only magnetic momentarrow_forwardDetermine the electronic configuration (in the form t2g "eg or emt2" , as appropriate) and the ligand field stabilization energy for each of the following complexes (1)[Co(NH3)6] 3* ; (II) [Fe(OH2)6] 2+arrow_forward
- Tetrahedral complexes such as [FeF4]2- possess a Td symmetry, as indicated in the picture below. Use group theory and symmetry operations to determine the reducible representation resulting from the combination of y vectors. Break the reducible into irreducible and decide which metal orbitals are likely used to form σ bonds.arrow_forward(a) Draw all possible isomers of the octahedral complex [CoCl2(en)(NH3)2]*, where en is the bidentate ethylenediamine ligand. Name the isomers and identify their point group symmetry. (b) With the aid of simplified molecular orbital energy level diagrams, explain why the 18-electron rule applies to metal complexes of all coordination numbers and not just six coordinate complexes.arrow_forwardThe two egorbitals are identical in energy in an octahedralcomplex but have different energies in a square planar complex,with the dz2orbital being much lower in energy than the dx2-y2 .Explain with orbital sketches.arrow_forward
