Synthesis and characterization of two-dimensional fluorinated metal phosphates incorporating 2,2′-bipyridine ligands: M2F2(2,2′-bpy)(HPO4)2(H2O) (M=Fe, Ga)

New Ternary Complexes of Copper(II) with 2,2′‐Bipyridine (Bpy) and Phosphocholine (PCh–) or the Quaternary 1‐(2‐Phosphonomethoxy)ethyl Derivative of 2,4‐Diaminopyrimidine (PMEDAPy–)

“…Solid metal phosphates and phosphonates are receiving much attention [1,2] because of their interesting magnetic and electronic properties. [3] They also have promising potential for applications in different areas: supports for catalysts, [4] as sensors [5] , and in nonlinear optics.…”

[Zn(H2PO4)4]2− clusters and ∞[Zn2(HPO4)3(H2PO4)2]4− layers in two new zinc phosphates templated by [H2(4-amino-2.2.6.6-tetramethylpiperidine)]2+ cations

“…5). 4 ] tetrahedra with two additional terminal phosphoryl groups linked to each zinc tetrahedron. Until now, these cyclic units were considered to be the starting building blocks of the vast majority of (ZnPO) with higher network dimensions, as illustrated by the schematic reaction pathway proposed by Neeraj et al [12].…”

“…3b) result from the condensation of two [Zn(H 2 PO 4 ) 4 ] 2À polyanions (Fig. 2a) 4 ] reveals a total weight loss of 36.9% (calculated: 37.7%) in two steps between 475 and 773 K (Fig. 7).…”

“…1.520 ( 1.526 (4) that the Bravais network is C centred. Owing to the very small size of the crystal, numerous reflections were very weak and the reflections with I44sðIÞ were only used.…”

“…During the past decade, the interest in the field of open-framework metal phosphates, in particular those of zinc, has considerably increased, as a reason of their potential catalytic activities and their rich structural chemistry [1][2][3][4]. Thus, more than 80 phases of organically templated zinc phosphates (ZnPO) have been prepared and characterized [5].…”
