Sitarski, J. Lipkowski   Guest-host and ligand-ligand interactions in solid clathrates of the [Ni(4-Mcpy)4(NCS)2] -nG type have been studied.

Using statistical methods it was found that there exists a nearly linear Ra vs.R e inverse correlation among the metal-ligand distances within the host coordination polyhedra.

Ossolińskich Wrocław 2 days ago  A clathrate is a chemical substance consisting of a lattice that traps or contains molecules. The word clathrate is derived from the Latin clathratus (clatratus), meaning ‘with bars, latticed’. Traditionally, clathrate compounds are polymeric and completely envelop the guest molecule, but in modern usage clathrates also include host–guest complexes and inclusion :// Lipkowski, J.
