Formation of bilayer structure through face-to-face π–π interactions
摘要:
Self-assembly of Cd(NO3)(2)center dot 4H(2)O and N,N,N ''-tris(4-pyridinylmethyl)-1,3,5-benzene tricarboxamide (L) in DMF and further diffusion into ether furnished a new 2D coordination polymer, [CdL2(NO3)(2)]. 2DMF (1) having noninterpenetrating honeycomb-like layer with (6,3) topology containing 54-membered rings and was characterized by elemental analyses, FT-IR, TGA and X-ray crystallography. These 2D sheets stack through face-to-face pi-pi interactions between central benzene rings and hydrogen bonding to form a bilayer structure. This type of perfect face-to-face pi-pi interactions (termed as Piedfart assemblies) are rare between benzene rings and its derivatives. (C) 2008 Elsevier B.V. All rights reserved.

isophthalic acids with general formulas [Cd2 (L)(NIP)2 (H2 O)2 ].4H2 O}n , (CP-1), [Cd2 (L)(AIP)2 (H2 O)2 ].4H2 O}n , (CP-2) and [Cd(L)(BIP) (H2 O)].4H2 O}n , (CP-3). The substituent groups on the co-ligand had profound effect on the network topologies of the corresponding CPs as well as their properties. Out of the three, CP-1 and 2 were found to form 3D networks whereas CP-3 was a 1D linear chain
Abstract Four Cd/Zn coordination frameworks, namely, [Cd(TPBA-4)(NO 3 ) 2 ]·2DMF·1.22H 2 O ( 1 ), [Cd(TPBA-4)(NO 3 ) 2 ]·H 2 O ( 2 ), [Cd(TPBA-4)(NO 3 ) 2 ]·2.2Me 2 CO·0.32H 2 O ( 3 ), and [Zn(TPBA-4)(NO 3 ) 2 ]·1.5Me 2 CO ( 4 ) were synthesized by the reaction of N′,N″,N‴-tris(pyrid-4-ylmethyl)-1,3,5-benzenetricarboxamide (TPBA-4) with the corresponding d 10 metal salts.
