Abstract
[CoPy4Cl2]·CHCl3 (Py=pyridine, C5H5N) clathrate was first synthesized and studied by single crystal X-ray diffraction analysis at 150 K (KM-4 diffractometer, λMoKα radiation, graphite monochromator, ω/2θ scan mode, θmax=35°,5894 reflections, R=0.043). The crystals are monoclinic; the unit cell parameters at 150 K are: a=14.76(2), b=9.40(1), c=17.645(6) Å, β=92.18(5)0, Z=4, space group P21/c, dcalc=1.536 g/cm3. The structure is of molecular-island type and consists of asymmetric distorted octahedral complex molecules of trans-[CoPy4Cl2] (host) and CHCl3 (guest). In addition to van der Waals contacts between the guest and host, shortened C−H...Cl and Cl...Cl distances have been found.
