    Notes: The title compound, poly[[diaquadibromocadmium-μ-(1,3,5,7-tetraazatricyclo[3.3.1.13,7]decane-N1:N5)-aquacadmium-di-μ-bromo-aquacadmium-μ-(1,3,5,7-tetraazatricyclo[3.3.1.13,7]decane-N1:N5)-di-μ-bromo] dihydrate], [Cd3Br6(C6H12N4)2(H2O)4]·2H2O, is made up of two-dimensional neutral rectangular coordination layers. Each rectangular subunit is enclosed by a pair of Cd3(μ2-Br)6(H2O)3 fragments and a pair of (μ2-hmt)Cd(H2O)2Br2(μ2-hmt) fragments as sides (hmt is hexamethylenetetramine). The unique CdII atom in the Cd2Br2 ring in the Cd3(μ2-Br)6(H2O)3 fragment is in a slightly distorted octahedral CdNOBr4 geometry, surrounded by one hmt ligand [2.433 (5) Å], one aqua ligand [2.273 (4) Å] and four Br atoms [2.6409 (11)–3.0270 (14) Å]. The CdII atom in the (μ2-hmt)Cd(H2O)2Br2(μ2-hmt) fragment lies on an inversion center and is in a highly distorted octahedral CdN2O2Br2 geometry, surrounded by two trans-related N atoms of two hmt ligands [2.479 (5) Å], two trans-related aqua ligands [2.294 (4) Å] and two trans-related Br atoms [2.6755 (12) Å]. Adjacent two-dimensional coordination sheets are connected into a three-dimensional network by hydrogen bonds involving lattice water molecules, and the aqua, bromo and hmt ligands belonging to different layers.

    Notes: Abstract In this paper, the stress and strain structures of Mode I 3-D crack in power hardening material are studied by analyzing the fundamental equations of elastic-plastic mechanics. It is shown that three regions, Z1,Z2 and Z3 can be divided in the thickness direction according to the stress characteristic. In region Z1, the stress components in the plane Perpendicular to z axis (thickness direction) can be solved first using the fundamental equations of plane strain state; in region Z3, they can be solved first by the equations of plane stress state. The region Z2 is defined as a transition layer. It is shown that the transition layer is the characteristic of Mode I 3-D crack in elastic-plastic state, and it is significant to the research on 3-D fracture. The crack tip opening displacement CTOD is chosen to describe the amplitude coefficient of the local stress field, and the distribution of CTOD in 3-D state is investigated.

    Notes: Abstract Two cadmium(II) complexes of betaine (BET) have been prepared and characterized by X-ray crystallography. [Cd(BET) (μ−Cl)2]∞ (1), is a one-dimensional polymer in which each cadmium atom is coordinated by two pairs of bridging chlorine atoms [Cd-Cl=2.631(2), 2.614(2) Å] and two oxygen atoms from different bridging carboxylate groups [Cd-O=2.291(6), 2.329(6) Å] in the form of a compressed octahedron. [Cd(BET)(H2O)Cl(μ−Cl)]2 (2) is a dimer with each cadmium atom in a distorted octahedral coordination environment, being surrounded by a chelating bidentate carboxylate group [2.480(2), 2.332(3) Å], one aqua ligand [2.364(3) Å], two bridging chlorine atoms [2.659(1), 2.557(1) Å], and one terminal chlorine atom [2.480(1) Å].
