A Combined Experimental and Theoretical Study on the Formation of a Cyclic Tetrameric Water Cluster and a Similar Type of Cyclic Cluster in Copper(II) Schiff Base Complexes

Abstract: Two copper(II) complexes, [CuL1]⋅2H2O (1) and [CuL2]⋅H2O (2) [where H2L1 {= N,N′‐bis(3‐methoxysalicylidene)propane‐1,3‐diamine} and H2L2 {=N,N′‐bis(3‐ethoxysalicylidene)propane‐1,3‐diamine} are potential hexadentate N2O4 donor compartmental Schiff bases], were synthesized and characterized. In each complex, copper(II) was placed in the inner N2O2 environment, with a four‐coordinate distorted square planar environment keeping the outer O4 compartment pendant. Lattice water molecules were hydrogen bonded with th… Show more

“…62 The bands in the range of 2840-2960 cm À1 due to alkyl C-H bond stretching vibrations are customarily noticed in the IR spectrum of the complex. 63 A distinct band is observed at 3351 cm À1 due to O-H stretching vibrations of coordinating water molecule and lattice water molecule. 64 Electronic spectrum of the complex has been recorded in DMF medium.…”

“…Nonetheless, the (H 2 O) 8 cubic cluster [4,85] has structural parallels with the [X 2 (H 2 O) 6 ] 2− cubes and the cyclic tetramers (H 2 O) 4 with the [Cl 2 (H 2 O)] 2− squares, although the hydrogen‐bonding arrangements are necessarily very different [86,87] . The water clusters typically have a variety of similarly‐stable (but not identically‐stable) hydrogen‐bonding arrangements depending on the locations of the dangling OH groups, for example, (H 2 O) 4 has four dangling OH groups (compared to [Cl 2 (H 2 O) 2 ] 2− with none) which may be on (i) different O atoms and up or down (to give a variety of isomers) with respect to the (OH) 4 ring, [86] (ii) two on one of the O atoms, or (iii) two on each of two O atoms in a D 2d structure that most resembles the dichloride dihydrate square [87] ). Halide‐water clusters, however, appear to each have only one type of hydrogen‐bonding arrangement (which may have two equivalent forms in the cases of (OH) x rings or chains).…”

“…Herein we have a cyclic tetrameric water cluster originated by the interactions of both encapsulated and non‐encapsulated water molecules. Different configurations are possible for this kind of tetrameric clusters which includes polar and non‐polar tetramer and also different topologies like uudd, C 4 , udud and D 2h are reported for these cyclic tetramers . The tetrameric water cluster present in our system is of D 2h symmetry and it is shown in Figure b.…”

“…It is very interesting to note that three distinct water molecules present in the system including the encapsulated water make a cluster in this crystal system. From the literature reports it is noted that these type of water clusters can adopt different configurations such as discrete chain (D), discrete ring (R), infinite chain in 1‐D without a ring (C) and also unclassified structures (U) etc . Herein we have a cyclic tetrameric water cluster originated by the interactions of both encapsulated and non‐encapsulated water molecules.…”
