In the title compound, C(12)H(8)F(2)O(2)S, which is a precursor of functionalised poly(aryl-ene ether sulfone) polymers, the dihedral angle between the aromatic ring planes is 84.43 (8)°. In the crystal structure, aromatic π-π stacking [centroid-centroid separations = 3.808 (3) and 3.867 (3) Å] helps to establish the packing. A short C-H⋯F contact also(More)
Platinum group metals (PGMs), i.e., palladium (Pd), platinum (Pt) and rhodium (Rh), are found at pollutant levels in the environment and are known to accumulate in plant and animal tissues. However, little is known about PGM toxicity. Our previous studies showed that chick embryos exposed to PGM concentrations of 1mL of 5.0ppm (LD50) and higher exhibited(More)
The asymmetric unit of the title compound, (C(23)H(33)N(2))[Li(C(32)H(16)N(8))]·0.5C(3)H(6)O·H(2)O, consists of two symmetry-unrelated lithium phthalocyanine (LiPc(-)) half-anions, centered at (1,0,0) and (0,,0), respectively, the bis-(adamant-yl)imidazolium cation (BAI(+)), occupying a general site, an acetone mol-ecule, disordered about the inversion(More)
