摘 要: | The present paper covers syntheses and crystal structures of benzyl- and cy-clopentyl-cyclopentadienyl sodium tetrahydrofuranate complexes C6H5CH2C5H4Na·THF (1) and C5H9C5H4Na°THF (2). X-ray diffraction data of the title compounds were collected at a low temperature (about 210K). Structures of both the crystals belong to monoclinic space group P21/n with α=0. 9316(3) nm, b=1. 5161(4) nm, c= 0.9791(3) nm, β=91. 06(3)°Z=4 for (1) and α=1. 6120(7) nm, b=0. 9370(3) nm, c=1. 8475(7) nm, β=109.52(3)°Z = 8 for (2). Both structures were solved by using direct methods and refined by block-matrix least-squares to final values of R = 0. 044 for 520 observed reflections (1) and R = 0. 067 for 921 observed reflections (2). In the crystals the tetrahydrofuranate complexes C6H5CH2C5H4Na·THF and C5H9C5H4Na·THF adopt a puckered chain structure with η5-(C6H5CH2)C5H4 and η5-(C5H9)C5H4 rings connected by a bridge Na (THF) unit.
