✦ Synopsis

For both structures all hydrogens were located in difference Fourier syntheses. The structures were refined by least-squares methods (OWLS ' ' 1 ; scale factor, isotropic extinction parameter, position parameters, anisotropic thermal parameters for non-Hatoms, isotropic thermal parameters for H) to final weighted R-factors of 6.1% for 1. uronium nitrate (1:l) and 5.6% for 2. Crystal Structure of 18-Crown-6 Uronium Nitrate (1:l) and Benzo-27-Crown-9 Uronium Perchlorate (1:l)
