“…Reid et al reported the crystal of [Mn 2z (H 2 O) 2 (15-crown-5)]Br 2 , in which [Mn 2z (H 2 O) 2 (15crown-5)] units are connected by H … Br bonds and they form an infinite columnar structure. 7 In the present crystal, the nitrogen atoms of CH 3 CN interact with the K z , and each SC z (supramolecular cation) unit associates with an adjacent SC z unit through the CH 3 CN-CH 3 CN dipole-dipole interaction. In each column, V-shaped SC z units are aligned in the same direction along the b-axis one-dimensionally with the two benzene rings towards the a-axis.…”

“…4 Weak interactions such as hydrogen bonding and p-p interactions are utilized to construct infinite columns and chiral double-helices, which are important models in biological systems. [5][6][7][8] The cation structure largely affects [Ni(dmit) 2 ] 2 arrangements within the crystals. We introduced supramolecular cation structures composed of inorganic metal cations-crown ethers as a counter cation for [Ni(dmit) 2 ] 2 anionic species.…”

K(dibenzo-18-crown-6)[M(dmit) 2 ](CH 3 CN) 2 (M ~Ni, Au), which have a one-dimensional supramolecular array, have been prepared. These salts are isomorphous and each K z (dibenzo-18-crown-6) suparamolecular cation unit is connected through the interaction of two CH 3 CN molecules. The [Ni(dmit) 2 ] 2 molecules exist as isolated monomers, and the magnetic susceptibility of the salt exhibits Curie-type behavior.

Crown-ether coordination compounds with Mn2+ and Sn2+ as cations and 12-crown-4, 15-crown-5, and 18-crown-6 as ligands are synthesized. Their luminescence properties and quantum yields are compared and correlated with their structural features. Thus, MnI2(15-crown-5) (1), MnCl2(15-crown-5) (2), [Mn(12-crown-4)2]2[N(Tf)2]2(12-crown-4) (3), Sn3I6(15-crown-5)2 (4), and SnI2(18-crown-6) (5) are obtained by an ionic-liquid-based reaction of MX 2 (M: Mn, Sn; X: Cl, I) and the respective crown ether. Whereas 1, 2, and 5 exhibit a centric coordination of Mn2+/Sn2+ by the crown ether, 3 and 4 show a sandwich-like coordination of the cation with two crown-ether molecules. All title compounds show visible emission, whereof 1, 2, and 5 have good luminescence efficiencies with quantum yields of 47, 39, and 21%, respectively. These luminescence properties are compared with recently realized compounds such as Mn3Cl6(18-crown-6)2, MnI2(18-crown-6), Mn3I6(18-crown-6)2, or Mn2I4(18-crown-6), which have significantly higher quantum yields of 98 and 100%. Based on a comparison of altogether nine crown-ether coordination compounds, the structural features can be correlated with the luminescence efficiency, which allows extraction of those conditions encouraging intense emission and high quantum yields.

The known metal-CO structures may be divided into two modifications, α and β. The α-modification has an order-disorder struxture, revealing one-dimensional disordering of the metal-oxalate chains, and the β-modification is ordered. The crystal structures of orthorhombic γ-MnCO {poly[μ-oxalato-manganese(II)]; space group Pmna, a = 7.1333 (1), b = 5.8787 (1), c = 9.0186 (2) Å, V = 378.19 (1) Å, Z = 4 and D = 2.511 Mg m} and γ-CdCO {poly[μ-oxalato-cadmium(II)]; space group Pmna, a = 7.3218 (1), b = 6.0231 (1), c = 9.2546 (2) Å, V = 408.13 (1) Å, Z = 4 and D = 3.262 Mg m} have been obtained from powder diffraction patterns. The structures are isostructural. Each metal atom in each structure is coordinated by seven O atoms which belong to five oxalate ions. The crystal packing, which contains noticeable cavities in the [101] and [001] directions, is not close packed and essentially differs from the known disordered α- and ordered β-modifications of transition metal oxalates. This modification seems to be metastable. It was found that a spontaneous γ→β phase transition takes place for γ-CdCO.
