What is the space group and unit cell parameters of any type of a Ni Complex ? What crystal class does this space group belong to?
Homework Answers
Space group is a combination of translational motion of the lattice with other motions such as rotational and/or vibrational motion.If the space group is assigned incorrectly then whole structure that is derived will be wrong.
Space group of any Ni complex is m3(bar)m.
This space group belongs to cubic class. Therefore shape of conplex would be cubic.
The cell parameters for such a complex is
a=b=c ( all sides equal)
all angles are equal and of 90.

three-dimensional analogs of a piece of wallpaper. Wallpaper has a
regular repeating design that extends from one edge to the other.
Crystals have a similar repeating design, but in this case the
