Non-order–disorder allotwinning of the rhenium pincer complex cis-Re[(PNP(CH2)-iPr)(CO)(2)Cl]

Crystals of cis-Re[(PNP(CH2)-iPr)(CO)(2)Cl] (1) are made up of two geometrically non-equivalent polytypes with respective symmetries of P2(1)/c and I2/a. The structures were determined in a concurrent refinement, taking into account overlap of diffraction spots. The polytypes are composed of layers...

Sumario:Crystals of cis-Re[(PNP(CH2)-iPr)(CO)(2)Cl] (1) are made up of two geometrically non-equivalent polytypes with respective symmetries of P2(1)/c and I2/a. The structures were determined in a concurrent refinement, taking into account overlap of diffraction spots. The polytypes are composed of layers with p (x)12(1)/c1 symmetry and are of the non-order–disorder (OD) type (the layer interfaces are non-equivalent). Whereas the molecules of (1) differ in both polytypes, the Re atoms are located at nearly identical positions.
