Diaquabis(ethylenediamine-κ²N,N′)zinc(II) bis(4-aminonaphthalene-1-sulfonate) dihydrate

Abstract

In the title compound, [Zn(C2H8N2)2(H2O)2](C10H8NO3S)2·2H2O, the ZnII cation lies on an inversion centre and has a distorted octahedral coordination geometry, defined by four N atoms from two ethylenediamine ligands and two water O atoms. In the crystal structure, pairs of 4‐aminonaphthalene‐1‐sulfonate anions are connected via N—H...O hydrogen bonds to form centrosymmetric R22(16) rings. Cations, anions and water molecules are further connected by N—H...O, O—H...O and O—H...N hydrogen bonds and π–π stacking interactions [with a centroid‐to‐centroid distance of 3.5099 (13) Å] to form a three‐dimensional network.

“…[33][34][35] In the structure of III,{ V 15 }c lusters are connected to their nearest neighbors by a[ Zn(en) 2 ] 2 + complex throughO term ÀZnÀ O term interactions to form ac hain directed along [101] ( Figure 6). [23,[36][37][38][39][40][41] The second unique Zn 2 + cation is in a distortedo ctahedral environment made up of three bidentate phen ligands (Tables S3, S5, and S6). The coordination environment is completed by bonds to terminal Oa toms of adjacent clustera nions( ZnÀO: 2.241(4) ), thus leading to ad istorted octahedral [Zn(en) 2 O 2 ] complex( Ta bles S3, S5, and S6).…”

Two novel mixed-ligand complexes containing organosulfonate ligands

“…For 4-aminobenzenesulfonate, it is common that the two functional groups simultaneously bind to metal ions; however, to our knowledge, no example of such behavior has been reported for 4-aminonaphthalene-1-sulfonate (ans). As part of an investigation of the coordination behavior of sulfonates, a series of mixedligand complexes have been synthesized so far; in our previous work, the sulfonate group behaved only as a charge-balancing counter-anion (Li et al, 2005a(Li et al, ,b, 2006(Li et al, , 2007. In order to obtain complexes in which the sulfonate group binds directly to the metal, ligands with a large conjugate plane, examples being 2,2 H -bipyridine, 1,10-phenanthroline and dipyridophenazine, were used as ancillary ligands.…”

A Novel Organosulfonate Cadmium(II) Complex with Graphite‐like 2D Layer Linked by Hydrogen Bonds

“…The Cd–O distance is with 2.336(2) Å slightly longer than the Cd–O(W) distance in[Cd(hmt) 2 (H 2 O) 4 ] 2+ (2.2915 Å)23 and [Cd 3 (hmt) 2 (fum) 2 (H 2 O) 6 ] 2+ (2.312(2) Å) 30. The bond lengths and angles around the sulfur atom are in agreement with those observed for similar compounds, including the modest opening of the O–S–O angles and narrowing of the O–S–C angles from the ideal tetrahedral value 17,31…”
