A vanadyl phosphate containing a new member of tancoite-like single chain,(DAPH2)[VIVO(HPO4)2]·xH2O(x≈0.2,DAP=1,3-diaminopropane,C3H10N2),has been synthesized under hydro(solvo)thermal conditions.It crystallizes in orthorhombic space group P21212(No.18)with a=7.1730(14),b=19.252(4),c=8.6557(17),Z=4,V=1195.3(4)3,C3H14.38N2P2VO9.19,Mr=338.47,Dc=1.881 g/cm3,μ(MoKα)=1.138 mm–1and F(000)=692.The final full-matrix least-squares refinement converged to R=0.0408,wR=0.1046 for 2498 observed reflections with I>2(I)and R=0.0456 and wR=0.1080 for all data(2750)and S=1.001.Its one-dimensional structure consists of tancoite-like1{VIVO(HPO4)2}2–single chains surrounded by DAPH22+ions and water molecules.The single chain is built from trans-corner-sharing octahedral{VIV=O···VIV}backbone loop-branched by HPO4groups like staple forming a new member of tancoite single chain.Due to the special coordination of VIVO6,the1{VO(HPO4)2–}chain adopts a larger M–O–M angle(V–O–V=135o)than those of tancoite chains reported before.The corner-sharing linear{VIV=O···VIV}chain structure also leads to a one-dimensional weak antiferromagnetic interaction at low temperature.The magnetic measurements confirm the 4+valence state of vanadium.IR and TG results of the title compound are also discussed.
A vanadyl phosphate containing a new member of tancoite-like single chain, (DAPH2) [VIVO (HPO4) 2] xH2O (x≈0.2, DAP = 1,3- diaminopropane, C3H10N2) thermal conditions. It crystallizes in orthorhombic space group P21212 (No.18) with a = 7.1730 (14), b = 19.252 (4), c = 8.6557 (17), Z = 4, V = 1195.3 .38N2P2VO9.19, Mr = 338.47, Dc = 1.881 g / cm3, μ (MoKα) = 1.138 mm -1 and F (000) = 692. The final full-matrix least-squares refinement converged to R = 0.0408, wR = 0.1046 for 2498 observed reflections with I> 2 and R = 0.0456 and wR = 0.1080 for all data (2750) and S = 1.001.Its one-dimensional structure consists of tancoite-like1 {VIVO (HPO4) 2} chains surrounded by DAPH22 + ions and water molecules. The single chain is built from trans-corner-sharing octahedral {VIV = O · VIV} backbone loop-branched by HPO4groups like staple forming a new member of tancoite single chain. the special coordination of VIVO6, the1 {VO (HPO4) 2-} chainage a larger M-O-M angle (V-O-V = 135o) than tho se of tancoite chains reported before. The corner-sharing linear {VIV = O · VIV} chain structure also leads to a one-dimensional weak antiferromagnetic interaction at low temperature. The magnetic measurements confirm the 4 + valence state of vanadium. IR and TG results of the title compound are also discussed.
