چکیده
A new 3D lead borate Pb(6)B(6)O(14)(OH)(2)(H(2)O), built by different cluster building units of B(6)O(14)(OH) {B(6)} and Pb(6)O(5)(OH) {Pb(6)}, has been obtained under mild hydrothermal conditions. Each {B(6)} cluster is linked with seven {Pb(6)} clusters and vice versa that give rise to the first 7-connected lead borate network.

Structural Investigation, Physical and Optical Properties of Mixed Alkali Bismuth Borate Glasses
Lead free, eco-friendly bismuth borate glasses doped with alkali oxides of composition xLi2O+(30-x)Na2O+55B2O3+15Bi2O3 (x = 5,10,15,20,25) were prepared by melt quenching technique. Amorphous nature of glasses was confirmed by X-ray diffraction. Density measurements were carried out at room temperature by standard principle of Archimedes with Xylene as an immersion liquid. The non-linear ...

A chromium borophosphate-phosphate (Na(8)[Cr(4)B(12)P(8)O(44)(OH)(4)][P(2)O(7)]nH(2)O, 1), which has an unusual 3D framework structure, was synthesized under hydrothermal conditions. The framework consists of spherical cages composed of CrO(6), PO(4), BO(4), and BO(3) polyhedra. The cages are located at the vertices and the body center of the cubic cell and are interconnected through 12-membere...
