“…There are several copper(II) dimeric compounds in which the copper atoms are bridged by chlorido ligands (Marsh et al, 1983;Puschmann et al, 2001;Li et al, 2006;Lee, et al, 2008;Han et al, 2008;Øien et al, 2013;Choubey et al, 2015;Golchoubian & Nateghi 2016;Liu et al, 2009). A search of the Cambridge Structural Database (Version 5.38, November 2016; Groom et al, 2016), revealed numerous di--chlorido bridged copper(II) compounds constructed with ligands having -N,O-donor atoms (Kapoor et al, 2002(Kapoor et al, , 2004Damous et al, 2013;Lumb et al, 2013;Smolentsev et al, 2014;Qureshi et al, 2016).…”

The 4-cyanobutyl group of (4-cyanobutyl) [3,4-lutidine](dimethylglyoximato) [O-(diphenylboryl)dimethylglyoximato]cobalt(III) was isomerized to the 1-cyanobutyl group with retention of the single-crystal form, although the corresponding cobaloxime complex without diphenylboryl in the equatorial ligands did not show such a photoisomerization. The trans-cis-cis conformation of the 4-cyanobutyl group caused by the steric repulsion from the diphenylboryl group is favorable to the crystalline-state reaction. In order to elucidate the detailed isomerization mechanism, two hydrogen atoms of the 4-cyanobutyl group were replaced with the deuterium atoms such as -CH 2 CH 2 CH 2 CD 2 CN. After the photoisomerization, the crystal structure with deuterated 4-cyanobutyl group was analyzed by neutron diffraction. Only one of the two deuterium atoms of the 4-cyanobutyl group was transferred to the C 1 atom such as -CD(CN)CH 2 CH 2 CDH 2 . This result made clear that the photo-produced cyanobutyl radical turned upside down after homolytic cleavage of the Co-C bond, and then the Co(II) atom and the radical made a bond to form the 1-cyanobutyl group.
