Which of the following statements is/are true of bonding in complex ions?
1. A complex ion with a coordination number of 3 has an octahedral arrangement of ligands and that complexes with two ligands are linear.
2. An octahedral set of orbitals is formed by the hybridization of one d, one s, and two p orbitals to give six dsp² orbitals.
3. For a tetrahedral arrangement of ligands, an sp³ hybrid set is required.

The correct statement is 3, which correctly describes the hybridization for a tetrahedral arrangement of ligands as sp^3. Statement 1 is incorrect because a complex ion with a coordination number of 3 would not have an octahedral arrangement (octahedral coordination typically involves 6 ligands), and complexes with two ligands are typically linear due to sp hybridization. Statement 2 is incorrect because the hybridization described does not correspond to any known hybridization scheme for octahedral complexes, which typically involve d^2sp^3 hybridization for a coordination number of 6.
