Synthesis and characterization of two new cadmium phosphonocarboxylates Cd2(OH)(O3PC2H4CO2) and Cd3(O3PC2H4CO2)2·2H2O

Structures and luminescent properties of lanthanide phosphonates

“…By slow evaporation of an acidic mixture of lanthanide nitrate or perchlorate salt and 2,2 -diethoxy-1,1 - 4 ]·xH 2 O (Ln = La, Ce, Pr, Nd, Sm, Gd, Tb, x = 9-14) were synthesized by the Lin group [33]. The lanthanide(III) center is 8-coordinate with four phosphonate oxygen atoms from four bisphosphonates ligands and four aqua ligands (Fig.…”

“…By using m-HO 3 S-C 6 H 4 -PO 3 H 2 (H 3 L 17 ) as the primary ligand and 1,10-phenanthroline (phen) or N,N -piperazinebis(methylenephosphonic acid) (H 4 L 2 ) as the auxiliary ligand, six novel lanthanide(III) sulfonate-phosphonates based on two types of tetranuclear clusters, namely, [La 2 (L 17 ) 2 (phen) 4 [64]. Their structures feature isolated, 1D and 3D tetranuclear lanthanide clusters.…”

“…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.…”

“…The selected unit (a) and a 1D cluster chain along the a-axis in [La 2 (L 17 ) 2 (phen)4 (H 2 O)]·4.5H 2 O (b).The CPO 3 and CSO 3 tetrahedra are shaded in medium and light gray, respectively. La and C atoms are drawn as open and black circles, respectively.…”

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].…”
