Syntheses, structures and properties of two molybdenum phosphates [(H20P8MoV12 CdO62) (C4H14N3)2]·2C4H13N3·8H2O and [(H2P2MoVI5 O23) (C4H14N3) (C4H15N3) (H3O)]·3H2O

Hydrothermal syntheses and crystal structures of two new phosphomolybdates based on an organoamine template

“…The colors of both compounds are related to charge-transfer transitions. Similarly, some reported Strandberg-type phosphomolybdates with Mo VI are colored[38,39].…”

Structural characterizations and magnetic properties of three new reduced molybdenum phosphates

“…3b) mode and free dien. Z 1,2,3 coordination mode [37][38][39][40] and free dien [5,41] have been reported, while Z 1,2 coordination mode of dien in present paper is first reported.…”

“…An important subclass of the POMs family is the reduced molybdenum phosphate based on the association of {Mo v 2 O 4 } fragments and PO 4 tetrahedra with structural range from zero to three dimensions, and in those intriguing structures [P 4 Mo 6 ] cluster units formed from {Mo v 2 O 4 } and PO 4 are firstly connected by metal-oxygen polyhedra producing M[P 4 Mo 6 ] 2 building blocks which are further linked by transition metal complexes or metal-oxygen polyhedra to result in extended structures. To our knowledge, in reported to date 38 compounds containing M[P 4 Mo 6 ] 2 building blocks there are 2 zero- [4,5], 15 one- [6][7][8][9][10][11][12][13][14][15][16][17][18], 8 two- [19][20][21][22][23][24][25] and 13 three-dimensional [9,10,14,[26][27][28][29][30][31][32][33][34] structures. It can be seen that zero-dimensional compounds containing M[P 4 Mo 6 ] 2 building unit are rare.…”

“…It can be seen that zero-dimensional compounds containing M[P 4 Mo 6 ] 2 building unit are rare. In reported compounds involving the above-mentioned structure unit, there exist a variety of sandwich atoms M including Na + [6,16,24,27], Cr III [23], Mn II [7,14,15,22,25,28], Fe II [4,[11][12][13], Fe III [20,26], Co II [8,14,18,30,31], Ni II [21,34], Zn II [10,18,19,33] and Cd II [5,9,10,29,32]. Here we report syntheses, structural characterizations, magnetic properties and photoluminescence of three new reduced molybdenum phosphates, [Co(dien) 2 ] Á (H 3 dien) 6 …”

Investigation of the Crystal Structure, Characterization, Hirshfeld Surface, and Theoretical Study of (C6H14N)5[HP2Mo5O23]·4H2O

“…The frequencies between 1530 and 1340 cm –1 are assigned to the C–N and C–C stretching vibrations of the organic part . Remaining bands between 1650–1100 cm –1 are associated to O–H bending of water molecules, also, N–H and C–H bending vibrations , . The second region (between 1100–400 cm –1 ) contain bands attributed to the cluster vibration.…”
