“…"Water clusters" have extensively been studied both theoretically and experimentally. In fact, the presence of water is important in establishing H-bonded contributions to the total lattice energy, and is significant in establishing the stability of the hydrated crystal structure [2][3][4]. On the other hand, water could be viewed as playing a spacefilling role in cases where there are cavities of a suitable size as a result of the close packing of the inorganic crystal structures.…”

Water clusters", group of water molecules held together by hydrogen bonds, have been the subject of a number of intense experimental and theoretical investigations because of their importance in understanding cloud and ice formation, solution chemistry, and a large number of biochemical processes. "Water clusters" can play an important role in the stabilization of supramolecular systems both in solution and in the solid state and there is clearly a need for chemists a better understanding of how such aggregates influence the overall structure of their surroundings. The present brief review deals with (H 2 O) n clusters, identified/observed crystallographically upon 170 crystal structures of synthesized coordination compounds based upon proton transfer compounds by Hossein Aghabozorg's research groups since 2000. The structural details of water clusters, (H 2 O) n , n = 2, 3,4,5,6,7,8,9,15,16 and are described systematically.

“…The hydrogen bond interactions as a kind of non-covalent interactions play an important role in forming various supramolecular frameworks. The hydrogen bond interactions not only expand the low structures through the effect of connection, but also generate the diverse water clusters, such as tetramers, pentamers, hexamers, octamers and decamers [4][5][6][7]. On the other hand phenanthroline complexes are well known for decades [8] and are still of general interest [9].…”

CCDC no.: 1541178The crystal structure is shown in the figure. Hydrogen atoms are omitted for clarity. Tables 1 and 2 contain details on crystal structure and measurement conditions and a list of the atoms including atomic coordinates and displacement parameters. Source of materialAll reagents and solvents employed are commercially available and used as received. A mixture of pyrazolecarboxylic acid (H 2 pca) (0.0224 g, 0.2 mmol), Mn(OAc) 2 ·4H 2 O (0.0245 g, 0.1 mmol), phenanthroline (phen) (0.0198 g, 0.1 mmol) and distilled water (10 mL) was sealed in a 23 mL Teflon-lined steel vessel (pH 4.4) and heated at 180°C for 72 h, then cooled to room temperature at a rate of 0.1°C min −1 . The resulting yellow block crystals were washed with distilled water. The yield is ca. 35% based on Mn. Experimental detailsH atoms attached to C atoms were placed in geometrically idealized positions (C-H 0.93 Å) and treated as riding on their parent atoms, with U iso (H) = 1.2Ueq(C). The water H-atoms were located in a difference Fourier map, and were defined with distance restraint of O-H = 0.82 Å and U iso (H) = 1.5Ueq(O). DiscussionThe assembly of supramolecular architectures based on non-covalent interactions has been developed in the field of supramolecular chemistry and crystal engineering [1][2][3]. The hydrogen bond interactions as a kind of non-covalent interactions play an important role in forming various supramolecular frameworks. The hydrogen bond interactions

“…Until now, a number of different discrete water clusters, namely tetrameric, [7] hexameric, [8] octameric, [9] decameric, [10] undecameric, [11] dodecameric, [12] tetradecameric, [6f] hexadecameric, [13] and heptadecameric [14] clusters have been structurally characterized and assigned different conformations. However, the units in these clusters are all small water clusters.…”

One novel N‐[(3‐carboxyphenyl)sulfonyl]glycine (H3L1) ligand (1) was prepared in high yield, and its structure was determined by single‐crystal X‐ray diffraction. Reaction of H3L1 with Mn(ClO4)2·6H2O at different pH values gave two new dinuclear complexes: [Mn2(HL1)2(phen)4]·16H2O (2) and [Mn2L1(phen)4(H2O)]ClO4·3H2O (3) (phen = 1,10‐phenanthroline). Additionally, two copper(II) complexes, [K2Cu(L2)2(H2O)2]n (4) and [CuL2(H2O)]2·2H2O (5), involving another novel ligand, N,N′‐(1,3‐phenylenedisulfonyl)bis(glycine) (H2L2), were prepared by a one‐pot reaction of 1,3‐phenylenebis(sulfonyl chloride), glycine, and KOH or triethylamine in the presence of CuII ions. A self‐assembled (H2O)30 cluster containing a puckered (H2O)12 ring core was found in 2, which presents a new mode of association of water molecules not predicted theoretically or previously observed experimentally. Furthermore, 2 forms a 2‐D supramolecular structure through hydrogen bonding and unique π–π stacking interactions. In 3, there also exist discrete trimeric water clusters. The identity of the base determines the specific structural characteristics of 4 and 5. When potassium hydroxide was used for the synthesis of 4, it led to a 3‐D copper(II)–potassium(I) coordination polymer; when triethylamine was used, paddle‐wheel dinuclear units of copper(II) carboxylate were produced. Magnetic measurements show that there are weak antiferromagnetic interactions in 2–4. In 5 the χMT vs. T curve shows a minimum at 110 K and a climb from 110 K to 5 K, then a long‐range antiferromagnetic ordering occurs, as revealed by a decrease in χMT with T.
