Bis(3-cyano-pentane-2,4-dionato) Co(II) as a linear building block for coordination polymers: combinations with two polypyridines

Trinodal Self-Penetrating Nets from Reactions of 1,4-Bis(alkoxy)-2,5-bis(3,2’:6’,3’’-terpyridin-4’-yl)benzene Ligands with Cobalt(II) Thiocyanate

“…We have recently reviewed our own progress in the coordination chemistry of ditopic and tetratopic ligands with 4,2':6',4''-tpy metal-binding domains [21]. The coordination behavior of bis(3,2':6',3''-tpy) remains little explored [13,22]. Rotation about the inter-ring C-C bonds in 3,2':6',3''-tpy (shown in red in Scheme 3) results in conformational changes that, in turn, define the vectorial arrangement of the nitrogen lone pairs in the metal-binding domains (Scheme 3).…”

Engineering 2D→2D parallel interpenetration using long alkoxy-chain substituents

“…An alternative strategy for increasing the dimensionality of the coordination architecture is to design multitopic 4,2':6',4''-tpy ligands. However, despite the successful use of polytopic 2,2':6',2''-tpy ligands for the construction of multinuclear assemblies [22][23][24][25][26][27] or for enhancing electronic communication between metal centres [28,29], little attention has been paid to the coordination potential of multitopic 4,2':6',4''-tpys [30][31][32][33]. Scheme 1.…”

Divergent 4,2′:6′,4′′- and 3,2′:6′,3′′-terpyridines as linkers in 2- and 3-dimensional architectures

“…In 2013, Yoshida et al demonstrated the potential for such ditopic ligands in reactions of 13 or 14 (Scheme 6) with bisIJ3-cyanopentane-2,4-dionato)-cobaltIJII). 39 Ligands 13 and 14 are both 4-connecting, and the combination of bisIJ3-cyanopentane-2,4-dionato)cobaltIJII) with 13 gives 2-dimensional nets that are triply interpenetrating.…”
