X-ray crystal structure of Cu(bipy)3(ClO4)2

Tris(2,2′-bipyridyl-κ2 N,N′)copper(II) hexafluoridophosphate

“…The structures of tris(2,2 0 -bipyridyl)copper(II) perchlorate (Anderson, 1972;Liu et al, 1991;Majumdar et al, 1998;Pavlishchuk et al, 1999) and tris(2,2 0 -bipyridyl)copper(II) tetraphenylborate (Murphy et al, 2006) have been reported previously. Here, we present the crystal structure of the title compound, (I), a hexafluoridophosphate salt that resulted from a study of room temperature in situ ligand substitution .…”

Structural systematics of the [Cu(chelate)3][Y]2series. An interesting crystallographic structural insight involving vibronic coupling and the Jahn–Teller effect (JTE). The syntheses and low temperature crystal structures of tris(2,2′bipyridyl)copper(ii) tetraphenylborate and tris(2,2′bipyridyl)zinc(ii) tetraphenylborate

“…28 In the crystal structure determination of 4b, one of the perchlorate groups also was disordered, but the structure refined to a slightly improved R-value of 0.062. 29 In the crystal structure determination of 4c, disorder was still present in the perchlorate, but the structure refined to a much better R-value of 0.035. 30 Pavlishchuk and coworkers also reported a similar R-value, in the crystal structure determination of 4d, of 0.0393.…”

Tris(2,2′-bipyridine-κ2N,N′)copper(II) bis(tetrafluoridoborate)

“…Metal complexes with three (modified) 2,2′-bipyridine ligands are of continous interest (Janiak et al, 1999;Wu et al, 2003;Yang et al, 2004a,b). Tris(2,2′-bipyridine)copper structure are known with the anions tris(oxalato)chromate(III) (Juric et al, 2006), polyoxovanadate (Dong et al, 2006), polyoxotungstate (Niu et al, 2004), bis(bis(2-thioxo-1,3-dithiole-4,5-dithiolato)-nickelate(II) (Faulmann et al, 1998), tetraphenylborate (Murphy et al, 2006) and perchlorate (Anderson, 1972;Liu et al, 1991;Majumdar et al, 1998;Pavlishchuk et al, 1999). The closely related tris(5,5′-dimethyl-2,2′-bipyridine)copper(II) complexes have been reported as the hexafluorophosphate (Perkins et al, 2006) and tetrafluoroborate salt (van Albada et al, 2004).…”
