catena-Poly[[[2-(2-chlorophenoxy)-N'-(2-oxidobenzylidene-κO)acetohydrazidato-κ2N',O]copper(II)]-μ-morpholine-κ2N:O].

In the title compound, {[Cu(C15H11ClN2O3)(C4H9NO)]n, the Cu(II) cation has square-pyramidal geometry. The morpholine ligand serves as a bridge to link two symmetry-related metal atoms, resulting in an infinite chain structure along the a axis. Adjacent chains are extended into a two-dimensional layered structure via hydrogen bonds formed between morpholine and amide N atoms [N-H···N = 2.

catena-Poly[[(2,2'-bipyridyl)oxidovanadium]-di-mu2-oxido-[(2,2'-bipyridyl)oxidovanadium]-mu3-selenito-bis[(2,2'-bipyridyl)dioxidovanadium]-mu3-selenito].

In the title compound, [V(4)O(8)(SeO(3))(2)(C(10)H(8)N(2))(4)], there are two distinct vanadium coordination environments. Alternating corner-shared VO(4)N(2) octahedra and SeO(3) pyramids result in eight-membered centrosymmetric V(2)Se(2)O(4) rings. In addition, pairs of V centres form centrosymmetric V(2)O(6)N(4) clusters via edge-sharing.

Bis(mu-4-carboxy-2-sulfonatobenzoato)bis[aqua(2,2'-bipyridyl)manganese(II)].

In the title compound, [Mn(2)(C(8)H(4)O(7)S)(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], pairs of hexacoordinated manganese(II) centres are bridged by 2-sulfonatoterephthalate(2-) anions to form cyclic centrosymmetric dimers, which are linked into sheets by O-H...

The crystal structure of the 1:1 inclusion complex of beta-cyclodextrin with benzamide.

The 1:1 inclusion complex of beta-cyclodextrin and benzamide was prepared and characterized by single crystal X-ray diffraction, PXRD, TGA, and IR. This complex crystallizes in the monoclinic P2(1) space group with unit cell constants a=15.4244(16), b=10.
