Clathration effects on the interpenetration in the 2D (4,4) coordination polymer {[Fe(4,4 ′ -bipy)(dca) 2 ] · bt}
Abstract A novel 2D polymer, {[Fe(4,4′-bipy)(dca)2] · bt}, (dca=dicyanamide, 4,4′-bipy=4,4′-bipyridine and bt=2,2′-bithiazoline) has been synthesized and characterized by X-ray crystallography. The structure reveals the formation of 2D (4,4) networks and intercalated bt uncoordinated ligands.
[CoII(4-terpyridone)2]X2: a novel cobalt(II) spin crossover system [4-terpyridone = 2,6-bis(2-pyridyl)-4(1H)-pyridone].
[EN] The cationic complex [Co(4-terpyridone)(2)](2+) where 4-terpyridone is the terpy-like ligand 2,6-bis(2-pyridyl)-4-(1H)-pyridone has been synthesized. High-spin and different spin crossover behaviors have been observed in the solid state depending on the counterion SO42-, Cl-, or ClO4-. The room temperature crystal structure of the spin crossover compound [Co(4-terpyridone)(2)](ClO4)(2).H2O is described.
