Poly[propane-1,3-diammonium [tetra-micro3-oxo-hexaoxotrimolybdenum(VI)] dihydrate].

The crystal structure of the title compound, [(C(3)H(12)N(2))[Mo(3)O(10)].2H(2)O](n), is composed of [Mo(3)O(10)](2-) anionic chains, propane-1,3-diammonium cations and solvent water molecules. The [Mo(3)O(10)](2-) chain is constructed from edge-sharing MoO(6) octahedra.

Tris(ethylenediamine)zinc(II) molybdate(VI), [Zn(en)3][MoO4].

The crystal structure of the title compound, [Zn(C2H8N2)3][MoO4], is composed of [MoO4]2- anions and [Zn(en)3]2+ complex cations (en is ethylenediamine), both with symmetry 2, which are held together in a three-dimensional network via hydrogen-bonding interactions. The [Zn(en)3]2+ cations in the crystal structure exhibit two configurations, viz. Lambda(deltadeltadelta) and Delta(lambdalambdalambda), as a pair of enantiomers.

[Repair of femoral neck fracture with vascular pedicled periosteum flap transfer in young and middle-aged].

Objective: To estimate clinical effect of spin iliac deep vascular pedicled periosteum flap in repairing traumatic femoral neck of theca inside fracture in young and middle-aged.

Methods: From April 1993 to September 2001, 12 cases of traumatic femoral neck fracture were given diaplastic operation with fixation of 3 centre hollow pressed bolt and were conducted under os traction bed and "C" arm X-ray machine. Spin iliac deep vascular pedicled periosteum flap was stripped off, and transferred to the front of femoral neck fundus, then transplanted to the narrow inside of fracture through outer open door of articular capsule.
