Crystal structure of penta­kis­(ethyl­enedi­amine-κ2 N,N′)lanthanum(III) trichloride–ethylene­diamine–dichloromethane (1/1/1)

We report here the crystal structure of a ten-coordinate lanthanum(III) metal coordinated by five bidentate ethyl-enedi-amine ligands, [La(C2H8N2)5]Cl3·C2H8N2·CH2Cl2. One free ethyl-enedi-amine mol-ecule and three Cl(-) anions are also located in the asymmetric unit. The overall structure is held together by an extensive hydrogen-bonding network between the Cl(-) anions and the NH groups on the...

Crystal structure of trans-(dicyano)bis(triphenylphosphine)palladium(II) dichloromethane solvate.

was obtained from the reaction of Pd(PPh3)4 with Me3SiCN (1:1 molar ratio) in benzene (at 80 ̊C for 2 h). Crystals suitable for X-ray diffraction analysis were obtained by recrystallization from a mixture of CH2Cl2 and C6H6 (ca. 1:4 by volume). Table 1 summarizes the crystal and experimental data. During the data collection at room temperature, decay was not observed. All intensity data were cor...

SYNTHESIS 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 ...

Melioidosis is an infectious disease caused by Burkholderia pseudomallei and endemic in Southeast Asia. One hundred and forty six clinical isolates of B. pseudomallei from different states in Malaysia were obtained and molecular typing was carried out using pulsed-field gel electrophoresis (PFGE). Overall, nine clusters were successfully identified. Burkholderia pseudomallei isolates used in th...
