Heteroligand complexes of Zn(II) diisopropyl dithiocarbamate with 1,10-phenanthroline and 4,4 '-bipyridlne. Crystal and molecular structures of clathrate compound Zn,(4,4 '-Bipy)((i-C3H7)(2)NCS2)(4)center dot 2C(6)H(5)CH(3)

Heteroligand compounds ZnPhen(i-Pr2NCS2)(2), Zn-2(4,4'-Bipy)(i-Pr2NCS2)(4), and Zn-2(4,4'-Bipy)(i-Pr2NCS2)(4) . 2C(6)H(5)CH(3) were synthesized. Singl e crystals were grown, and the structure of clathrate compound Zn2(4,4'-Bip y)(i-Pr2NCS2)4 2C6H5CH3 was determined by X-ray diffraction analysis (CAD-4 diffractometer, MoKalpha radiation, 3976 F-hkl, R = 0.0468). The crystals are monoclinic: a = 8.458(2), b = 33.668(7), c = 11.754(2) Angstrom, beta = 110.68(3)degrees, V = 3131(1) Angstrom(3), Z = 2, p(calcd)= 1.248 g/cm(3), space group P2(1)/c. The structure is formed from the discrete centrosymme tric binuclear Zn-2(4,4'-Bipy)(i-Pr2NCS2)(4) molecules and toluene molecule s. The coordination polyhedron of the Zn atom is a tetragonal pyramid forme d by four S atoms of two bidentate-cyclic dithiocarbamate ligands and one N atom of the bidentate-bridging 4,4'-Bipy ligand. Toluene molecules are sit uated in cavities formed by the C atoms of the Zn-2(4,4'-Bipy)(i-Pr2NCS2)(4 ) complex. The compounds were studied by IR spectroscopy and thermal analys is.
