That does seem wrong. Is /dev/mapper/sdc3_xcrypto shown by
lvdisplay/lvs? Because it is not, you probably should not try to mount
it.

thank you, but for some reason I can't quite understand, I haven't
found a thorough, self-describing step-by-step guideline about such
matters and I don't have the time right now, Internet access to make

You're trying to mount lvm2 physical volume which is never going to
work - it's not a filesystem.
What you should mount is a logical volume, i.e. that devices that
lvdisplay shows you.

I (wrongly) think I have done everything right but I can't mount the
encrypted drive
