Build a crystal with atoms coordinates and lattice information

Dear All
I'm trying to build a mineral stucture with the atom coordinates and lattice information from litterature. It's a amorphous structure. I set the space group as P1. I added the bonds manually. If I l look at the cell from one direction, it looks normal. But after I rotate it, the bonds look like been stretched. I attached the pictures, is that normal?

Thank you!
