摘要
cis-Tetrakis(isothiocyanato)(triphenylphosphine)(triphenyl-phosphine oxide)rhenium(IV), [Re(NCS)4(Ph3P)(Ph3PO)], is formed during the reaction of [ReOCl3(Ph3P)2] and trimethylsilylisotbiocyanate, Me3SiNCS. The compound crystallizes monoclinic in the space group P2(1)/n, a=9.981(3), b=37.447(6), c=11.761(4) angstrom, beta=111.21(1)degrees and Z=4. Structure refinement converged at R=0.037. Pb3P and Ph3PO are cis-coordinated with Re-P and Re-O distances of 2.511(3) and 2.018(7) angstrom, respectively. The NCS ligands are coordinated via nitrogen.
