The structures of trimethylphenylphosphonium iodide, C9H14P+*I-, and (p-dimethylaminophenyl)trimethylphosphonium iodide, C11H19NP+*I-, have been determined at 100 K in order to study the substituent perturbation of the trimethylphosphonium group and the additional effect of a p-dimethylamino group.Trimethylphenylphosphonium iodide crystallizes in the orthorhombic space group Pca21 with two independent molecules in the asymmetric unit.The p-dimethylaminosubstituted compound has a planar amino group with an N-C(phenyl) bond distance in the double-bond range.Both structures contain short C-H...I distances below the sum of the van der Waals radii.
