Abstract

The three-dimensional metal complex inclusion compound $Cd(pn)Ni(CN)_4{\cdot}0.5NO_2C_6H_5$(pn: 1,2-diaminopropane=propylenediamine) crystallizes in the orthorhombic space group, $Pn2_1$a, (a=13.868(5), b=26.591(4), c=7.840(1)${\AA}$, V=2891(1)${\AA}^3$, Z=4), R=0.054 for 2800 independent reflections. The host structure of the inclusion compound appears the same one(T-type) of inclusion compound with branched aliphatic-guest molecule. The nitrobenzeneguest molecule attains the stable position in the nodal channel of T-type by placing the polar nitro group between the pn-amino groups at the node and the bulky aromatic ring in the antinodal zone of the channel. The substituted aromatic guest molecule is accommodated in the host structure of metal complex $Cd(pn)Ni(CN)_4$ with channel cavity.
