Synthesis, Crystal and Molecular Structure of Mono- and Diaquadi(acetato-O)-Bis(2,4′-Bipyridyl) Copper(II)

Diaquabis(2,4′-bipyridyl-N′)dichloromanganese(II)

“…(Sheldrick, 1997); program(s) used to re®ne structure: SHELXL97 (Sheldrick, 1997); molecular graphics: XP in SHELXTL/PC (Sheldrick, 1990) and ORTEP-3 (Farrugia, 1997); software used to prepare material for publication: SHELXL97. This work forms part of a continuing study of 2,4′-bipyridyl complexes with copper(II) and manganese(II) salts (Bartczak et al, 1998;Kruszynski et al, 2001). Although coordination compounds of these salts with 2,2′-bipyridyl and 4,4′-bipyridyl have been extensively investigated, there are only a small number of reports describing structures of 2,4′-bipyridyl complexes.…”

Modulatingp-hydroxycinnamate behavior as a ditopic linker or photoacid in copper(ii) complexes with an auxiliary pyridine ligand

“…Other interesting distances are between intrachain and interchain Cu(II), which are Cu1A⋯Cu1A 5.999 Å, Cu1B⋯Cu1B 5.999 Å and Cu1A⋯Cu1B 14.137 Å. Compared to similar 1D chain like structures, the interchain Cu⋯Cu distance is shorter when the carboxylate group belongs to acetate (around 8.2 Å) 44,46 or cinnamate (13.091 Å). 45 These chains are held together due to the role of the pOHcinn ligand.…”

“…All these distances and angles are in good agreement with related Cu(II) carboxylate-pyridine compounds. 14,44,45 Relevant distances and angles are summarized in Table 1.…”

“…Similar motifs have been reported before in our group and in the literature. 44,46 Each monomer 1A has a symmetric quadruple H-bond, involving the coordinated O1A from the pOHcinn ligand and H4AB of the coordinated H 2 O molecule (Fig. 1B).…”
