Huang and Xu argue that the cyclo-N-5(-) ion in (N-5)6(H3O)(3)(NH4)(4)Cl we described in our report is theoretically unfavorable and is instead protonated. Their conclusion is invalid, as they use an improper method to assess the proton transfer in a solid crystal structure. We present an in-depth experimental and theoretical analysis of (N-5)(6)(H3O)(3)(NH4)(4)Cl that supports the results in the original paper.
