“…The distance between the cobalt(II) ion and the symmetry related O1 and O1′ atoms (Fig. 2) (Smirnov et al, 1998) (Lee et al, 2002). This indicates that in (I) there is a short non-bonded contact between the cobalt ion and the crown ether molecule.…”

The asymmetric unit of the title compound, [Co(C44H28N4)]·C12H24O6, contains one half of a CoII(TPP) (TPP is tetraphenylporphyrin) complex and one half of an 18-crown-6 molecule of crystallization, both lying on inversion centers. The CoII(TPP) complex exhibits a nearly planar conformation of the porphyrinate core [maximum deviation = 0.069 (2) Å] with an average Co—N distance of 1.971 (4) Å. The distance between the Co atom and the closest O atom of the 18-crown-6 molecule is 2.533 (2) Å, indicating a short non-bonded contact between the Co atom and the crown ether molecule. An ethylene group of the 18-crown-6 molecule is disordered over two sites with occupancies of 0.565 (7) and 0.435 (7).

“…The literature provides many examples of such compounds, among which the most typical include: the acetate O atom acting as a linker between two metal atoms, e.g. between two K + cations, as in K 4 [Co(H 2 (Lee et al, 2002); or between one K + cation and another metal such as Fe, Sb or Mo (Solans et al, 1984;Ilyukhin & Petrosyants, 2001;Kneale & Geddes, 1975); or between one K + cation and a lanthanoid cation, as in K[Ho(C 10 (Sakagami et al, 1999). Furthermore, the carboxylate O atom of edta can bridge three metal atoms, as in the following examples: three K + cations, as in K 2 [Ga(C 10 H 12 -N 2 O 8 )(OH)]Á6H 2 O (Ilyukhin & Petrosyants, 2001); two K + cations and another cation such as a lanthanoid, as in K[Yb(C 10 H 12 N 2 O 8 )(H 2 O)]Á5H 2 O (Sakagami et al, 1997); or one K + cation and two transition metal centres, as in K[Mo 2 (C 12 H 15 N 2 O 10 )(OH) 2 ] (Kneale & Geddes, 1975 (Fig.…”

Three potassium edta (edta is ethylenediaminetetraacetic acid, H(4)Y) salts which have different degrees of ionization of the edta anion, namely dipotassium 2-({2-[bis(carboxylatomethyl)azaniumyl]ethyl}(carboxylatomethyl)azaniumyl)acetate dihydrate, 2K(+)·C(10)H(14)N(2)O(8)(2-)·2H(2)O, (I), tripotassium 2,2'-({2-[bis(carboxylatomethyl)amino]ethyl}ammonio)diacetate dihydrate, 3K(+)·C(10)H(13)N(2)O(8)(3-)·2H(2)O, (II), and tetrapotassium 2,2',2'',2'''-(ethane-1,2-diyldinitrilo)tetraacetate 3.92-hydrate, 4K(+)·C(10)H(12)N(2)O(8)(4-)·3.92H(2)O, (III), were obtained in crystalline form from water solutions after mixing edta with potassium hydroxide in different molar ratios. In (II), a new mode of coordination of the edta anion to the metal is observed. The HY(3-) anion contains one deprotonated N atom coordinated to K(+) and the second N atom is involved in intramolecular bifurcated N-H···O and N-H···N hydrogen bonds. The overall conformation of the HY(3-) anions is very similar to that of the Y(4-) anions in (III), although a slightly different spatial arrangement of the -CH(2)COO(-) groups in relation to (III) is observed, whereas the H(2)Y(2-) anions in (I) adopt a distinctly different geometry. The preferred synclinal conformation of the -NCH(2)CH(2)N- moiety was found for all edta anions. In all three crystals, the anions and water molecules are arranged in three-dimensional networks linked via O-H···O and C-H···O [and N-H···O in (I) and (II)] hydrogen bonds. K···O interactions also contribute to the three-dimensional polymeric architecture of the salts.

Molecular growth processes utilizing a beta-octamolybdate synthon and {Ag2} dimers are described and the directing influence of "encapsulating" cations and coordinating solvent is also demonstrated. The growth of two 1D chains, (nBu4N)2n[Ag2Mo8O26]n (1) and (nBu4N)2n[Ag2Mo8O26(CH3CN)2]n (2), is achieved when nBu4N+ ions are used, and the diameter of the chains can be expanded by the coordination of CH3CN solvent (2). The formation of a type of gridlike structure in which 1D chains are crossed-over each other in alternatively packed layers is achieved in DMSO as the solvent; DMSO acts as a linking group to give (nBu4N)2n[Ag2Mo8O26(dmso)2]n (3), which, similar to 1 and 2, still incorporates the Bu4N+ ions that exert an "encapsulating" influence. However, in (HDMF)n[Ag3(Mo8O26)(dmf)4]n (4) the relatively bulky Bu4N+ ions are exchanged for protonated DMF cations, thereby allowing the chains to condense to a 2D array. The building block concept is further enforced by the isolation of a "monomeric" unit (Ph4P)2[Ag2Mo8O26(dmso)4] (5), which is isolated when the Ph4P+ ions are so "encapsulating" as to prevent aggregation of the {Ag-Mo8-Ag} building blocks. The nature of the AgAg dimers in each of the compounds 1-4 is examined by DFT calculations and the interplay between these Ag-Ag interactions and the structure types is described.
