I can’t tell for Avogadro2 (problems installing/running repackaged version 1.95.1-2 as provided for Linux Debian 12/bookworm testing [tracker]) but an old installation of Avogadro 1.2.0 in Xubuntu 18.04 LTS reads the chloromethane/water model you pasted without problem.
What could be a hurdle – here it becomes a speculation – is the number of decimals about the coordinates or/and the alignment of these columns. Say, your model is saved in file
model_input.xyz and you run OpenBabel on the terminal like
obabel model_input.xyz -O reformat_output.xyz
then these entries are rounded to five decimals. This precision might be good enough for your work. Perhaps then the model is understood.
If you aim for an illustration of the model, and old Avogadro is not accessible for you, an other viewer e.g., Jmol may be an alternative. If you want to set up an additional computation e.g., Gabedit equally offers assistance for a couple of programs.
