Hm. Chawla et al., REACTION OF TETRASODIUMCALIX(4)ARENE SULFONATE WITH TRANSITION METAL(III) NITRATES (METAL = CR, CO AND FE), Indian journal of chemistry. Sect. A: Inorganic, physical, theoretical & analytical, 33(8), 1994, pp. 746-749
Reaction of tetrasodiumcalix(4)arene sulphonate (TSCS) with metal(III)
nitrates (metal - Cr, Co and Fe) provides a good yield of the corresp
onding complexes, viz., [Cr(OH2)6][Na][TSCS] (acetone).10.5H2O, [Co(OH
2)6][Na][TSCS].7.5H2O and [Fe(OH2)6][Na][TSCS].10H2O. The new complexe
s have been characterized by elemental analyses, magnetic susceptibili
ty measurements, IR and electronic spectral data.
