(CuBr)2P8Se3: preparation, structural, and vibrational spectroscopic characterization of an adduct of P8Se3 cages to Cu2Br2 rhombs

Abstract

Orange -red (CuBr) 2 P 8 Se 3 was obtained from stoichiometric amounts of CuBr, P and Se by melting and subsequent annealing at 380 8C for 1 month. The crystal structure was determined from single crystal X-ray data. (CuBr)

Structural characterization of MoOCl3(THF)2, the pre-reagent for Kauffmann olefination reactions

“…Single crystals of MoOCl 3 (THF) 2 were obtained during our explorative investigations of the reactivity of phosphorus chalcogenide cage molecules towards transition metal halides [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. We stirred 0.1 g Mo 2 Cl 10 (0.4 mmol, 1 eqiv.…”

Phosphorus Nanorods—Two Allotropic Modifications of a Long‐Known Element

“…[6][7][8][9][10][11] Furthermore, polymeric phosphorus strands are readily formed as their copper iodide adducts by treating stoichiometric mixtures of CuX (X = Br, I) with elemental P. Compounds of this kind include two different 1 1 [P 12 ] polymers in (CuI) 8 P 12 [12] and in (CuI) 3 P 12 , [13] Figure 1)-by a low-temperature route. [15] The copper iodide adducts were obtained by a typical high-temperature synthesis and the resulting crystalline materials were subsequently treated with an aqueous solution of potassium cyanide at room temperature.…”

Compounds of this kind include two different 1 1 [P 12 ] polymers in (CuI) 8 P 12 [12] and in (CuI) 3 P 12 , [13] respectively, and a 1 1 [P 14 ] polymer in (CuI) 2 P 14 . [14] The separation of the pure phosphorus strands from the copper halide matrix represents an intriguing chemical challenge and should help to verify the theoretical investigations.…”
