, p. 25 - 32 (1989)
SnH4 reacts with Fe2(CO)9 under restricted conditions to form the known compound Sn2 (1), and a new tin-iron cluster SnFe5(CO)19 (2).The crystal structure of 2 shows a structure with an Fe3 triangle edge-bridged by a SnFe2 one.Further tin-iron clusters are indicated.

Organomanganese complexes with tin atoms in linear and trigonal-planar coordination environments are accessible by means of two different synthetic methods.Sequential treatment of the complex (η5-C5H4CH3)Mn(CO)2(THF (1a) with tin(II) chloride and zinc dust yields (μ3-Sn)5-C5H4CH3)Mn(CO)2>3 (2a); 2a is also formed from 1a and monostannane, SnH4.The pentamethylcyclopentadienyl derivative 1b yields analogously the two compounds (μ3-Sn)5-C5Me5)Mn(CO)2>3 (2b) and (μ-Sn)5-C5Me5)Mn(CO)2>2 (3b). 2a formally contains two Mn-Sn single bonds and a Mn-Sn double bond (X-ray diffraction study). - Keywords: Bridging tin atoms/ Organomanganese complexes
Improved syntheses of M2 (M=Si, Ge or Sn) and the X-ray crystal structure of Si2
Anema, Skelte G.,Barris, Glen C.,Mackay, Kenneth M.,Nicholson, Brian K.
, p. 207 - 216 (2007/10/02)
The reaction of MH4 (M=Si, Ge) with Fe2(CO)9 in hexane gives Si2 or Ge2 in 61 or 43 percent yield, respectively.A reproducible synthesis of Sn2 from 2- and SnCl4 in thf is also described.The X-ray crystal structure of Si2 shows two mutually perpendicular SiF2 triangles linked at the common spiro-silicon atom, with each iron atom carrying four terminal CO ligands.Average bond length are: Fe-Si 2.345(4), Fe-Fe 2.795(3) Angstroem.
