Application of the Dimensional Reduction Formalism to Pb₁₂[Li₂(P₂O₇)₂(P₄O₁₃)₂](P₄O₁₃): a Phosphate Containing Three Types of Isolated P–O Groups

Abstract

A new phosphate, Pb12[Li2(P2O7)2(P4O13)2](P4O13), containing three types of isolated polyphosphate anionic groups [P2O7], and two types of [P4O13] has been successfully synthesized by using Li2O as dimensional reduction agent to dismantle Pb3P4O13. The isolation of [P2O7] and two types of [P4O13] with different symmetries in the title compound mainly benefits from the large number and flexible coordination of the Pb(2+) cations.

ALiZnP2O7 (A = Rb, Cs): Two Mixed Alkali Zinc Pyrophosphates Featuring a [Li2Zn2P4O20]14– Anionic Skeleton

“…The obtained band gaps of RLZP and CLZP with different arrangements of the Li/Zn atoms are given in Table . The theoretical band gaps of RLZP and CLZP (3.31 eV for RLZP-hyp01, and 3.34 eV for CLZP-hyp01) are smaller than those of the experimental (4.78 and 4.84 eV) results, which are consistent with the reported compounds . Furthermore, the obtained band gaps of RLZP-hyp01, RLZP-hyp02, RLZP-hyp03, CLZP-hyp01, CLZP-hyp02, and CLZP-hyp03 are similar to the experimental values, while the obtained band gaps of RLZP-hyp04 and CLZP-hyp04 are much smaller than the experimental values, indicating that the Li/Zn atoms may be arranged alternately in the Li/Zn layers in the compounds (shown in Figures and S3).…”

“…Under the guidance of this design, many NLO phosphates were discovered, such as LiCs 2 PO 4 , RbBa 2 (PO 3 ) 5 , Ba 5 P 6 O 20 , RbBa 2 (PO 3 ) 5 , Rb 2 Ba 3 (P 2 O 7 ) 2 , KLa­(PO 3 ) 4 , RbNaMgP 2 O 7 , CsNaMgP 2 O 7 , and so on . Besides outstanding performances, there are some excellent structural compounds, such as A 3 Sr 2 P 7 O 21 (A = Rb, Cs), Cs 2 MgZn 2 (P 2 O 7 ) 2 , and Pb 12 [Li 2 (P 2 O 7 ) 2 (P 4 O 13 ) 2 ]­(P 4 O 13 ) . These compounds are rich in structural types and functional properties.…”

A2BBi2(PO4)2(P2O7) (A = K, Rb, B = Pb, Cd): the Effect of Cation Sizes on Structural Evolution

“…[ 14 ] As a result, a variety of compounds containing Pb 2+ , Bi 3+ have been reported with interesting structures, such as β ‐BiSeO 3 Cl with a giant unit cell, [ 15 ] Pb 12 [Li 2 (P 2 O 7 ) 2 (P 4 O 13 ) 2 ](P 4 O 13 ) containing three types of isolated P–O groups. [ 16 ] Recently, we have successfully synthesized two pyrophosphates NLO materials containing Pb 2+ and Bi 3+ , A 3 PbBi(P 2 O 7 ) 2 (A = Rb, Cs) with good performances. [ 17 ] Based on the above‐mentioned work, we obtained successfully two new compounds by cation modulation strategy, K 2 PbBi 2 (PO 4 ) 2 (P 2 O 7 ) ( I ) and Rb 2 CdBi 2 (PO 4 ) 2 (P 2 O 7 ) ( II ) with two kinds of P–O groups simultaneously.…”

Study of thermal dehydration of sodium orthophosphate monosubstituted

“…By using the method of solid-phase recovery, there was received the new compound Pb 12 [Li 2 (P 2 O 7 ) 2 (P 4 O 13 ) 2 ] (P 4 O 13 ), containing in its structure several polyphosphate groups [17]. In [18], a method of spontaneous crystallization was applied to synthesize polyphosphate, which contains two different polyphosphate anions.…”
