摘要:
Low pressure sublimation of tri-2,2′-bipyridinesilicon(0) leads to di-2,2′-bipyridinesilicon crystals. The unit cell is orthorhombic, space group Pbca, a 21.509, b 15.995, c 10.127 », Z = 8. The crystal structure was solved using 490 reflexions recorded at room temperature and refined down to a reliability index R = 0.046. The silicon atom is surrounded tetrahedrally by the bidentate 2,2′-bipyridine ligand with a mean NSiN angle of 100° and a mean SiN bond length of 1.72 ». © 1979.
