Crystallographic and Structural Analysis of Iron Heterometallic Compounds Part IV: Heteropentameric Compounds

“…As can be seen, the P 5 ligand is a cyclo 1' 5 with an envelope conformation. In the spirocycle, the planes P(3), Ir(l,2) and P (2,3,4), Fe are perpendicular (89°), the ligands at the Ir atoms are arranged trans. While the Ir(l) -Ir (2) Table 4 reveals that the shortest bond is the FeLi bond at 2.448(5)A.…”

“…In the structure of ruby red Fe 2 Ge 2 Pb complex [109], the lead(II) the Ir(I) Fe(l) Fe (2) and Ir(l)Au(l) Au(2) triangles. The dihedral angle between the planes is 86.0°.…”

“…Many structural studies of iron compounds have been published. To date these include comprehensive overviews of structural data for monomeric [1], dimeric and oligomeric iron coordination compounds [2], iron carbonyls [3] as well as heterobinuclear [4] and heterotrimeric iron clusters [5]. Variations and trends in bond lengths and angles were found and their importance was discussed in these reviews.…”

Structural characterization of heteropolymeric iron and main group metal complexes

“…In many cases, heterometal compounds have been prepared for which crystallographic and structural data have been obtained. The structural chemistry of 800 heterodimer iron compounds has been reviewed (Melnik et al , 2006 ), as well as over 350 heterotrimers (Melnik et al , 2007 ), almost 300 heterotetramers (Melnik et al , 2008 ), 180 heteropentamers (Melnik et al , 2010 ), 160 heterohexa and heteroheptamers (Melnik and Holloway , 2011 ), and 130 heteroocta and heterooligomer clusters (Mirskij , 2009 ). The structural chemistry of polymeric heterometal iron compounds, in which alkali metals are partners to the iron, has been reviewed recently (Meln í k et al, in press ).…”
