The Crystal Structures Of α,ω-Diaminoalkanecadmium(II) Tetracyanonickelate(II)-Aromatic Molecule Inclusion Compounds. II. 1, 6-Diaminohexanecadmium(II) Tetracyanonickelate(II)-o-Toluidine (1/1): Cd(NH₂(CH₂)₆NH₂)Ni(CN)_4. o-CH₃C₆H₄NH₂

Abstract

The title inclusion compound crystallizes in monoclinic space group P2/m, with a=9.541(2), b=7.569(2), and c=7.199(1) Å, β=100.3(l)°, and Z=l. The structure has been refined to a conventional R=0.036 for 1973 independent reflections collected by counter method. The host metal complex has the structure similar to that of 1,4-diaminobutanecadmium(II) tetracyanonickelate(II)-2,5-xylidine (1/1) with respect to the two-dimensionally extended wavy cyanometal complex sheets bridged by the α,ω-diaminoalkane ligands at the respective Cd atoms in adjacent sheets providing a channel-like cavity with the guest aromatic molecule. The guest o-toluidine molecule is surrounded by four 1,6-diaminohexane bridges taking an all-trans conformation of the aliphatic chain and show disorder in the orientation in the cavity.
