SYNTHESIS AND CRYSTAL STRUCTURE OF [Pph ] [WS (CUNCS) ] A. Taeb A. Beheshti and N.K. Javadi SYNTHESIS AND CRYSTAL STRUCTURE OF [Pph ] [WS (CUNCS) ]
The crystals of [WS (CuNCS) ] anion have been isolated from CH ,CI solution and examined by X-ray structural analysis as well as by IR spectroscopy. The unit cell is monoclinic with a= 14.3796(13), b= 18.039(1 I), c= 22.5956(23)& P= 96.053(8)', space group P2,/n (14), Z= 4. The crystal structure was refined by the least-squares calculations to a final R-value of 0.0398(Rw= 0.0443) for 2777 u...
متن کاملSynthesis and Crystal Structure of Cs3nb2br9, a Dinuclear Niobium Cluster
SYNTHESIS AND CRYSTAL STRUCTURE OF CS3NB2BR9, A DINUCLEAR NIOBIUM CLUSTER. The niobium bromide cluster compound, Cs3Nb2Br9, was obtained by solid-state synthesis techniques in reaction of stoichiometric amounts of CsBr, Nb powder and NbBr5. It crystallizes in the hexagonal system with unit cell parameters a = 7.7183(2) Å, c = 18.3396(7) Å, space group P63/mmc, Z = 2. Its crystal structure was d...
متن کاملSYNTHESIS AND CRYSTAL STRUCTURE OF [PPh ] [WOS (CUNCS) ]
The reaction of [PPhJ, NOS,] with CuCl and KSCN (1 :3:3) in acetone produces the yell-ow crystals of [PPh,], [WOS,(CuNCS),]. The crystals are triclinic, space group P1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), Y= 65.194(4)'. The crystal structure was determined by single crystal Xray diffraction methods (Mo-K ?) and refined by least-squares calculations ...
