- Work out the stoichiometries and structures of the neutral complexes, chromium carbonyl, rhenium carbonyl, and nickel carbonyl using the 18-electron rule. Then use valence bond theory to determine the hybridizations of the orbitals in each complex?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_forwardA 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_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_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_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_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_forwardTetrahedral 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
- Determine 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(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_forwardChemistry Calculate the gas phase or free ion term for a d8 transition metal ion and the ground and excited states and configurations that arise when this metal centre forms a tetrahedral complex. For each state, sketch the d-orbital splitting with appropriate symmetry labels and electron populationsarrow_forward
