Both the syn- and anti-isomers of TcN(bzdbsalpn) were formed in the solution, but recrystallization of a mixture of syn- and anti-TcN(bzdbsalpn) gave a single crystal only for the syn-isomer. X-ray crystallography showed that the syn-TcN(bzdbsalpn) was in a distorted octahedral structure. The planar tetradentate bzdbsalpn ligand coordinates to the technetium atom in an O-N-N-O equatorial plane and the six-membered Nimine-Nimine chelate ring that includes the propylene group adopts a chair conformation. The nitrido ligand (Tc≡N) is at an apical position and the Tc≡N triple bond length is 1.6Å. Interestingly, the crystal of syn-TcN(bzdbsalpn) has a nitrido-bridged linear polymeric structure (···Tc≡N···Tc≡N···) running along the 21 screw axes parallel to the b axis. The intermolecular N···Tc distance in the syn-TcN(bzdbsalpn) crystal (∼2.8Å) is fairly long compared with that reported for Cr(V) and Mn(V) nitrido complexes with analogous Schiff base ligands (∼2.5Å). © 2004 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Takayama Tsutomu aut Abe Yuko aut Sekine Tsutomu aut Kudo Hiroshi aut Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/4-6/2004(2004-04-01), 265-269 0033-8230 92:4-6/2004<265 2004 92 ract https://doi.org/10.1524/ract.92.4.265.35600 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/ract.92.4.265.35600 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Takayama Tsutomu aut NATIONALLICENCE 700 1- Abe Yuko aut NATIONALLICENCE 700 1- Sekine Tsutomu aut NATIONALLICENCE 700 1- Kudo Hiroshi aut NATIONALLICENCE 773 0- Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/4-6/2004(2004-04-01), 265-269 0033-8230 92:4-6/2004<265 2004 92 ract CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
