Luminescent coordination polymers of 2,2′-bipyrimidine and mercury(II) salts: A structural and computational study

“…However, few studies have been reported about the luminescence of d 10 metal complexes of bipym, and all focused on Zn(II) and Cu(I). In the zinc complexes, metal-ligand interactions are interpreted not unambiguously: their effect seems to have a modest effect on the electronic transitions of the ligand itself [8], or a MLCT is invoked [9]. For Cu(I) complexes of POP (bis{2-(diphenylphosphanyl) phenyl} ether) and phosphine a huge increase of the intensity of the luminescence and the apparition of new MLCT bands are reported [10].…”

Cationic tris(pyrazolyl)borate bipyrimidine complexes

“…2,2 0 -Bipyrimidine (bpym) is a useful ligand in coordination chemistry able to act as a chelating bidentate [1][2][3] or bridging bis-bidentate ligand [4][5][6][7][8][9][10][11][12][13][14]. [11,12].…”

“…[11,12]. More recently, hetereodinuclear systems have also been prepared [13]. Such complexes are of interest as the bpym ligand facilitates weak magnetic exchange between the metals which although antiferromagnetic in most cases can be ferromagnetic.…”

Homo-chiral self-assemblies and magnetic studies of M(II)-2,2′-bipyridine-4,4′-dicarboxylate coordination polymers

“…Since a formulation of χ for a helical chain of Ni(II) ions with ZFS will be complicated and the magnetic interaction in a chain will be small, taken into account ZFS of the Ni(II) atoms and interactions among Ni(II) ions in the molecular field approximation, χT of {Ni(bpdc)(H 2 O) 2 } n can be written as Eq. (3) [11][12][13], where the susceptibility χ′ of monomeric Ni(II) ion with ZFS is written as Eq. (4) [13,14],…”
