catena-Poly[[(triaquacadmium)-μ-1,4-phenylenediacetato-κ4O,O′:O′′,O′′′] dihydrate]

“…For other cadmium coordination polymers containing 1,4phda ligands, see: Wang & LaDuca (2010); Farnum et al (2011). T = 173 K 0.34 Â 0.32 Â 0.29 mm…”

“…ligands (Wang & LaDuca, 2010;Farnum, et al, 2011). The title compound was obtained upon an attempt to prepare a cadmium 1,4-phda coordination polymer incorporating 4,4′-trimethylenedipiperidine.…”

A NEW CRYSTALLINE FRAMEWORK FORMED FROM 1,4-bis(4-PYRIDYLMETHYL)PIPERAZINE AND Cd(NO3)2: INTERPENETRATING MOLECULAR LADDERS FROM T-SHAPED BUILDING BLOCKS

“…Employing of flexible bipyridyl ligands makes controlling of the eventual product more difficult, however, it provides more probability to achieve motifs with particular functions which are worth studying: (i) novel topological structures and framework entanglements (such as polycatenation and polythreading) [ 15 ]; (ii) variability of the networks (single or entangled) [ 16 ], and (iii) pleomorphism of conformation [ 17 ] that can result in a vatiety of chemical functions. Intriguingly, flexible bipyridyl ligands such as 1,4-bis(4-pyridylmethyl)piperazine (4-bpmp) [ 18,19 ] have not been much explored in comparision with the great effort aimed at the progress of compounds containing rigid bipyridyl ligands.…”
