  Synthesis, characterization, and structures of New Titanocene Isoselenocyanato Complexes

  摘要：

  AbstractThe complexes [Ti(η5‐C5H4R)2(NCSe)2] [R = Me (1), SiMe3 (2), or SiEt3 (3)] were prepared from the corresponding dichlorides with KSeCN in acetone; the oxygen‐bridged complex [Ti(η5‐C5H4Me)2(NCSe)]2O (4) was formed by air oxidation of (1). All complexes were characterized by elemental microanalysis and by IR, 1H NMR, and mass spectroscopies. An X‐ray analysis of (1) and (4) confirms the results of IR studies that these complexes contain N‐bonded selenocyanate ligands. In molecules (1) and (4) there is a pseudotetrahedral arrangement about each titanium. The NCSe chains are linear with normal NC and CSe bond distances. The dimer (4) contains an approximately linear TiOTi bridge (angle 173.4º) with a TiO bond distance of 1.838 Å. The structural results are compared with those in related compounds.
