For materials science, diamond crystals are almost unrivalled for hardness and a range of other properties. Yet, when simply abstracting the carbon-bonding structure, the corresponding periodic framework is far from rigid. We study the kinematics of this type of periodic bar-and-joint articulated system, with particular regard to the volume variation of a unit cell. For potential applications to nano-mechanism design, we determine conditions for planar auxetic behaviour.
