[N(CH3)4]2[Co2Mo6O12(OH)4(PO4)(HPO4)2(H2PO4)].5H2O, a New One-Dimensional Molybdenum Phosphate

Template Cooperation Effect Leading to the New Layered Aluminophosphate CN3H6·Al(HPO4)2·2H2O

“…The single distinct phosphorus center makes two P−O−Al bonds to two different adjacent aluminum atoms with a d av (P−O) value of 1.531(9) Å. There are two terminal P−O vertexes, one of which is short, indicating a degree of multiple bond character as also seen in C 5 NH 6 ·Al(HPO 4 ) 2 ·2H 2 O 18 and one of which is protonated, showing its characteristic lengthening . Bond valence sum (BVS) calculations for Al (2.89) and P (4.97) yielded typical values.…”

Two New Tetramethylammonium Zinc Phosphates: N(CH3)4·Zn(HPO4)(H2PO4), an Open Framework Phase Built up from a Low-Density 12-Ring Topology, and N(CH3)4·Zn(H2PO4)3, a Molecular Cluster

“…1 and the complete crystal structure is illustrated in Fig. 2 (23,24) suggest that the P(1)-and P(3)-centered groups are hydrogen phosphate entities and the P(2)-and P(4)-centered groups are dihydrogen phosphate moieties.…”

A novel 3D network structure constructed from centrosymmetric sodium-phosphomolybdate bonding by sodium and zinc atoms

“…A central phosphate group bridges the ring internally, and each one of the other three phosphate groups bridges one long MoÁ Á ÁMo contact externally. The four phosphorous atoms have P-O bond lengths between 1.508 (4) [14]. The two crystallographically independent Na atoms have a bond-valence sums of 1.56 for Na(1) and 1.00 for Na(2), respectively.…”
