from The Century Dictionary and Cyclopedia
- In crystallography, pertaining to the inclination of three intersecting axes to each other; specifically, appellative of a system of crystallization in which the three axes are unequal and their intersections oblique, as in the oblique rhomboidal prism. Also triclinohedric, triclinate, anorthic, asymmetric, tetartoprismatic. See cut 3 under rhombohedron.

Sorry, no etymologies found.
The crystal structure of the acid is triclinic, meaning its crystal system has 7 lattice points.
In the sixth and last system, the triclinic -- or anorthic, or asymmetric -- the axes are again three, but in this case, none of them are equal and none at right angles.

Beginning with the highest, we have -- (1) the cubic system, with nine planes of symmetry; (2) the hexagonal, with seven planes; (3) the tetragonal, with five planes; (4) the rhombic, with three planes; (5) the monoclinic, with one plane; (6) the triclinic, with no plane of symmetry at all.
