Talk:Orthorhombic crystal system

I would like to rename this and other articles so that all of the articles describing the seven crystal systems are named the same way. For example, I would like to rename this article Orthorhombic crystal system. That way it woun't be confued with the general gemetric shape. Any objections? O. Prytz 17:40, 5 June 2006 (UTC)


 * Need a compelling reason for such changes - not just a cosmetic thing, methinks. I really have no serious objection as long as you plan to fix the hundreds of existing links to the article (really only required if you plan this to be a disambiguation page). If some other use of orthorhombic shows up - simply add a disamb. link to the existing page - that's my lazy solution. Vsmith 23:55, 5 June 2006 (UTC)


 * There are several reasons that the changes should be made. First, the articles describing the seven crystal systems should use the same naming convention. That is, if we decide to stick with just Orthorhombic we probably should change Cubic crystal system (the current name) to just Cubic. Otherwise, I think all of them should be renamed as I have suggested. Second, I believe it is more correct to rename these articles as I have suggested, since they refer/describe specific usage in crystallography, and not the general geometric shapes.


 * When it comes to the technicalities of making these changes, my plan was just to copy the contents of the articles into new pages with the new names. Then just place a redirect on the old page. But maybe that's a too simple solution? O. Prytz 00:21, 6 June 2006 (UTC)


 * If there are no further objections, I'll probably make the suggested changes within a day or so (rename pages + add redirects at the old articles). O. Prytz 16:59, 7 June 2006 (UTC).

Some doubts arise.
When we describe a base centered orthorhombic system, how is the base defined? I think that part needs to be added. Because there are 3 different lattice parameters, how to decide the base? Not only that, each page on each Bravais Lattices doesnt contain enough of the properties, of the crystal, like 1)No of atoms contained. 2)Co-ordination number. 3)Packing fraction.

-- The # of atoms contained and the packing fraction depend on the actual molecule in the crystal; they are not properties of the lattice structure itself.

Origin of term orthorhombic? Where is there any rhombus?
I've been looking all over and I can't figure out what the orthorhombic system has to do with a rhombus, as all the faces are rectangles. The article could do well to contain such origin information.Nicknicknickandnick (talk) 19:59, 3 September 2015 (UTC)
 * This is not widely known, but there is another setting for the orthorhombic that uses a unit cell of a right rhombic prism. This is the reason why it's orthorhombic. Ortho=rectangle. Rhombic=rhombus. Both have the same symmetry which is why this crystal system has two possible axes.--Officer781 (talk) 03:20, 31 July 2016 (UTC)

Improve Figure
Could the figure showing the primitive lattice be changes so it doesn't look so much like a cube? — Preceding unsigned comment added by 131.156.157.1 (talk) 16:19, 14 April 2016 (UTC)

The Pictures in “Bravais lattices” Section
It seems that three-dimensional pictures of cells are incorrect. In the “Right rhombic prism unit cell” row, the first picture and the second one seems to be misplaced, so does the third one and the fourth one. I can’t confirm, though. -- Ný(rönn)-Holtredéþch-Deskrúð / Nyholtredehn Discussion! 12:21, 25 July 2018 (UTC)
