Abstract The crystal and molecular structure of trans-dichloro(4-methylpyrimidine)(η 1 -phenyl)cis-bis(pyridine)rhodium(III) water solvate, 1x 0.17H2 O, and trans-dichloro(η 1 -phenyl)tris(triphenylstibine)rhodium(III) ethylacetate solvate, 2x CH3 CO2 CH2 CH3 have been studied via X-ray diffraction from a single crystal at room temperature. The final refinement converged to R1 conventional index of
摘要反式二氯(4-甲基嘧啶)(η1-苯基)顺式-双(吡啶)铑(III)水溶剂化物,1x 0.17H2 O和反式二氯(η1-苯基)tris的晶体和分子结构通过室温下单晶的X射线衍射研究了(三苯基锑)乙酸乙酯(III)铑(III)溶剂化物。对于1x 0.17H2 O [空间群R(-3)和2x CH3 CO2 CH2 CH3 P(-1)的结构分析,最终的细化收敛到R1常规指数0.0350和0.0361。4-甲基嘧啶配体(Pym)仅与Rh in 1弱结合,如长Rh-N距离(2.251(4)A)所示,而Rh N(吡啶)的平均长度为2.066(4)。Pym和吡啶(Py)配体的涉及N供体的NC键距分别为1.329(6)和1.345(6)。供体上的CNC键合角对于Pym为114.1(5)°,对于Py平均为117.4(4)°。与以前在该实验室研究的相应丙酮溶剂化物的结构相比,2x CH3 CO2 CH2 C
