Synthesis and structural-bonding analysis of (.eta.5-C5H4Me)4Fe4(CO)6P8 and (.eta.5-C5H4Me)4Fe6(CO)13P8: two unprecedented transition-metal complexes containing the cage-like P8 subunit of Hittorf's monoclinic phosphorus allotrope

“…Hittorfs phosphorus allotrope (3) contains alternating P8 and P9 units linked by P2 chelating bridges. 35,38 In the a-P8 unit of interest, the bridged P5/P7 and P6/P8 pairs at 3.37 Á (av) are only 0.37 Á farther apart than the nonbridged P5/P8 and P6/P7 pairs. Thus, the two-atom P2 bridges induce minimal distortion on the P8 cage from its idealized nonbridged Z>2¿ geometry.…”

Chemical and Physical Properties of YHg3 and LuHg3

“…The Hg−Hg distances of 3.0678(8) Å (4×), 3.219(1) Å (2×), and 3.335(1) Å (2×) are comparable with the values of 2.993 and 3.465 Å observed for octahedrally coordinated atoms in α-Hg (at T = 78 K). 49 Calculation of the electron density (ED) and its analysis within the QTAIM approach reveal essential charge transfer from yttrium to mercury (Figure 7). The shapes of the atomic basins, obtained from the topological analysis of ED, show features characteristic of a charge transfer scenario.…”
