Inclusion of a well resolved T4(2)6(2) water tape in a H-bonded, (4,7)-binodal 3D network

Synthesis, structure, and properties of two novel copper(II) complexes, [Cu(phen)(L)2]·6H2O and [Cu(phen)3]·(ClO4)2

“…Although they are bond to the host via hydrogen bonds, the O7, O8, O9 and O10 are in three-coordinate configuration, while O6 is in tetrahedral arrangement. Within the water cage, the OÁ Á ÁO distances are in range of 2.744(3)-2.872(2) Å with a average of 2.827 Å, which is comparable to that observed in the ice P phase 2.77-2.84 Å [24], although the value is longer than that of average OÁ Á ÁO contact of 2.72-2.80 Å found in other (H 2 O) 10 clusters hosted by metal-organic frameworks [25][26][27]. Carboxyl groups provide potential hydrogen-bonding intermolecular interactions, besides its coordination ability towards metal ions.…”

Synthesis, Structures and Properties of Two New Coordination Polymers with Unprecedented Water Cluster

“…As far as we know, water clusters with (H 2 O) 10 are still very rare, the limited examples are included in the literatures [79,81]. Among these water clusters (H 2 O) 10 , most of them were T4(2)6(2) water tapes [79,80] or ten-membered rings [81], however, (H 2 O) 10 with T10(0)A0 has never reported prior to our work. Therefore, to some degree, this water morphology of 2 can also be viewed as (H 2 O) 20 cluster.…”

Crystal structure of [2-(triethylammonio)ethyl][(2,4,6-triisopropylphenyl)sulfonyl]amide tetrahydrate

“…Some recent structures involving water forming the T4(2)6(2) hydrogen-bonding motif have been published (Li, Li, Su et al, 2006;Li, Chen et al, 2006;Song et al, 2007;Kostakis et al, 2009). There are only a few examples of twodimensional hydrogen-bond networks known, but among these the L4(6)5( 7)6(8) motif is the most common.…”
