A Comparative Study of a Novel Microporous Indiumphosphate and Other M(III)X(V)O4-Type Microporous Materials

Hydrothermal synthesis and characterization of the first 1-D indiumphosphate chain In2(HPO4)2(H2PO4)2F2·C4N2H12, a precursor for high dimensional structures

“…P(2) atom also shares two oxygen atoms with adjacent In atoms, but the other two oxygen atoms are terminal PQO/P-OH groups (d Pð2Þ2Oð3Þ ¼ 1:496ð4ÞÅ) and P-OH group (d Pð2Þ2Oð8Þ ¼ 1:553ð4ÞÅ). These results are close to those observed previously in indiumphosphates [14][15][16][17][18][19][20][21][22][23][24][25][26]. The structure consists of infinite macroanionic chains of empirical formula [In 2 (HPO 4 ) 2 (H 2 PO 4 ) 2 F 2 ] 2À separated by PIP cations.…”

“…Carefully studying the transformation of different dimensional zinc phosphates, Rao and co-workers [12,13] believed that the zero-dimensional (0-D) monomers, comprising four-membered rings, are the basic structural units of the zinc phosphates and after an optimal precursor state, such as the ladder structure, to construct into high-dimensional structure. However, compared with the researches for the structural transformation mechanism on MPOs (M ¼ Al, Ga and Zn) families with the M of 4-, 5-and 6-coordination (or mixtures), the research for that on indiumphosphates is rearly documented, though it might be more readily understood because only rigid [17,18], 9/8 [19], 5/4 [20], 6.8/8 [21], and 2-D layers with In/P ratios of 1/3 [22], 1/2 [23][24][25], 4/7 [26], 1/1 [20] up to now. The low-dimensional indiumphosphate, such as 1-D chains and 0-D monomer, has not yet been discovered, which results that there is not sufficient data to systematically study the structural transformation mechanism.…”

Open-Framework Inorganic Materials

“…[93] Other structures, analogous to known minerals, have been isolated: a hydrated indium phosphate, InPO 4 -1, [96] related to the variscite type, and InPO 4 -2, [97] related to the leucophosphite type. These compounds are characterized by small pores delimited by eight polyhedra.…”

Anorganische Materialien mit offenen Gerüsten

“…Dieser Arbeit folgten mehrere andere Beispiele, die auf verschiedenen Aminen beruhten; [93±95] dazu gehörte auch eine verstrebte Schichtstruktur, die mit Imidazol hergestellt wurde (Abbildung 12). [93] Andere erzeugte Strukturen sind analog zu bekannten Mineralen aufgebaut: Ein hydratisiertes Indophosphat, InPO 4 -1, [96] ist mit dem Variscit-Typ und InPO 4 -2 [97] mit dem Leukophosphit-Typ verwandt. Charakteristisch für diese Verbindungen sind kleine Poren, die von acht Polyedern abgegrenzt werden.…”
