Phenol, having favourable physical and chemical properties, can be enclosed as the guest component in the clathrates of tetracyano complexes. Six compounds of Hofmann and similar type clathrates M(NH 3) 2M' (CN) 4.nG and M(en) m M'(CN) 4.nG were prepared and identified: Ni(NH 3) 2Pt.2C 6H 5OH; Ni(en) 2Pt(CN) 4.O.14C 6H 5OH; Ni(NH 3) 2Pt(CN) 4.C 6H 5OH.H 2O; Zn(NH 3) 2Ni(CN) 4.O.1C 6H 5OH.H 2O; Cu(NH 3) 2Ni(CN) 4. 2C 6H 5OH and Fe(NH 3) 2Ni(CN) 4.2C 6H 5OH. The phenol containing clathrates are more stable than clathrates containing other guest molecules. In the case of Ni(en) 2 Pt(CN) 4.O.14C 6H 5OH thermal loss of the guest molecule leaves the host lattice intact, but further heating results in the rupture of the host lattice. The compounds were capable in the solid state of sorbing other organic molecules once they had been heated to the temperature required for almost complete loss of guest molecule i.e. n→o.
