Synthesis and characterization of two manganese phosphonocarboxylates: Mn3(O3PCH2COO)2 and Mn3(O3PCH2CH2COO)2

Structures and luminescent properties of lanthanide phosphonates

“…The strategy of attaching functional groups such as crown ether, amine, hydroxyl, or/and carboxylate groups to the phosphonic acid has proven to be very effective for the isolation of a variety of metal phosphonates with open framework and microporous structures [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Most of the studies have been focused on first row transition metals, zirconium(IV) as well as E-mail address: mjg@ms.fjirsm.ac.cn.…”

Hydrothermal syntheses, characterizations and crystal structures of two new lead(II) diphosphonates with a layered and a microporous structure

“…Different from divalent transition metal complexes, lead(II) compounds have a unique coordination chemistry due to the presence of the lone pair electrons [4]. A number of lead(II) carboxylate-phosphonates and lead(II) aminodiphosphonates with layered or 3D network structures have been reported [5][6][7][8][9][10][11][12]. In order to understand the effect of the substituents attached on the structures of metal aminodiphosphonates formed, we have studied a number of divalent metal compounds with RN(CH 2 PO 3 H 2 ) 2 (R ¼ Me, C 6 H 5 -CH 2 -) [13,14].…”

Hybrid Organic-Inorganic Materials Based on Organophosphorus Derivatives

“…Carboxyphosphonic acids most often produce such pillared structures. This is illustrated by Zn 3 (O 3 PC 2 H 4 CO 2 ) 2 [33] or Co 3 (O 3 PC 2 H 4 CO 2 ) 2 [34] where metal atoms are found in tetrahedral as well as in octahedral coordination sites, by Mn 3 (O 3 PCH 2 CO 2 ) 2 where manganese atoms are found in octahedral, square pyramidal and tetrahedral coordination sites [35,36] and by Pb 3 (O 3 PCH 2 CH 2 CO 2 ) 2 where divalent lead atoms are found in three, four and five-coordination sites [37,38] ordination to the metal atom, it cannot bring anymore functionality to the material: therefore it is interesting to increase the number of functional groups. Phosphonate groups bearing aminoacid [42,43] [18].…”
