The title compound, 5-(4,5-dimethylthio-1,3-dithiol-2-ylidene)-1,3-diaza-2,4,6-trithiapentalene (4,5-dimethylthio [1,2,5]thiadiazolotetrathiafulvalene, molecular formula C(8)H(6)N(2)S(7)) crystallizes in the P2(1)/n space group with one molecule in the asymmetric unit. The molecular framework is planar within 0.19 A. The molecules form a head-to-tail type of pi-stacking dimer with an interplana...

The extraction of Gadolinium (Gd) from perchlorate and nitrate media in 1,2-dichloroethane(C2H4Cl2), carbon tetrachloride (CCl4) and chloroform (CHCl3) by mixtures of 2-thenoyltrifluoroacetone (HTTA) and a crown ether benzo-15-crown-5 (B15C5) is investigated.The composition of the extracted species is determined as Gd(TTA)3.nB15C5 (n=1 in nitratemedium and n=2 in perchlorate medium). The values...

Reaction of [U(TrenTIPS )(PH2 )] (1, TrenTIPS =N(CH2 CH2 NSiPri3 )3 ) with C6 H5 CH2 K and [U(TrenTIPS )(THF)][BPh4 ] (2) afforded a rare diuranium parent phosphinidiide complex [{U(TrenTIPS )}2 (μ-PH)] (3). Treatment of 3 with C6 H5 CH2 K and two equivalents of benzo-15-crown-5 ether (B15C5) gave the diuranium μ-phosphido complex [{U(TrenTIPS )}2 (μ-P)][K(B15C5)2 ] (4). Alternatively, reaction...
