The crystal be- longs to monoclinic, space group P21/n, a = 9.6808(2), b = 26.7204(5), c = 12.7993(3) , β = 100.9340(10)o, V = 3250.75(12) 3, Z = 4, Dc = 1.348 g/cm3, μ = 0.586 mm–1, F(000) = 1380, S = 1.131, R = 0.0689 and wR = 0.1883 for 4782 observed reflections (I > 2σ(I)). The title crystal consists of Co(II) complex and lattice water molecules. The Co(II) complex assumes a distorted octahedral coordination geometry, formed by one Schiff base dianion phenylenediamine-3-me- thoxysali-cylaldehyde and two imidazole ligands. The π-π stacking interaction occurs between nearly parallel benzene rings of the neighboring complexes.展开更多

The crystal belongs to mono- clinic, space group C2/c with a = 23.1905(14), b = 30.1877(12), c = 7.4881(3) ?, β = 97.631(2)o, V = 5195.8(4) ?3, Z = 8, Dc = 1.451 g/cm3, μ = 0.989 mm–1, F(000) = 2352, S = 1.030, R = 0.0694, wR = 0.2120 (I > 2σ(I)), R = 0.0950 and wR = 0.2322 (all data). The crystal consists of the Cu(I) complex and lattice water molecules. The Cu(I) atom is coordinated by two phenanthroline (phen) molecules and one chlorine anion with a distorted trigonal dipyramidal coordination geometry. By the aid of aromatic π-π stacking, the Cu(I) complex molecules form two-dimensional supramo- lecular layers. Lattice water molecules locate between the adjacent layers to form a three-dimen- sional sandwich-like supramolecular structure.展开更多
Ladder-like polyphenylsilsesquioxanes with fairly high regularity were synthesized using an endo-template 1,2-ethylenediamine at mild temperature via direct co-hydrolysis and condensation reactions in the presence of ...Ladder-like polyphenylsilsesquioxanes with fairly high regularity were synthesized using an endo-template 1,2-ethylenediamine at mild temperature via direct co-hydrolysis and condensation reactions in the presence of acid catalysts in the mixture of 1,4-dioxane/H2 O. The features for synthesis of ladder-like polyphenylsilsesquioxanes were investigated in detail. The products obtained were characterized by FTIR, SEC, XRD and NMR.展开更多
