Venetian-blind mechanism

Inorganic waad fran.y-[M(LOH)2X2] (M=Pd, Pt, X=C1, I, CH3COO, CH3) exploit this Venetian-blind mechanism to convert between the anion-mediated network of the apohost, sustained by OH... X hydrogen bonds, and the guest-mediated network based on OH... G hydrogen bonds [17], [25] . 

In the simplest form of a pulley, the grooved wheel is attached to seme immovable object, such as a ceiling or beam. When a person pulls down on one end of the pulley rope, an object at the opposite end of the repe is raised. In a fixed pulley of this design, the mechanical adwitage is cne. That is, a person can lift a weight equal to the force applied. The advantage of the pulley is me of direction. An object can be made to move upward or downward with such a pulley. Venetian blinds are a simple example of the fixed pulley.
