Title: Two isotypic diphosphates LiM{sub 2}H{sub 3}(P{sub 2}O{sub 7}){sub 2} (M=Ni, Co) containing ferromagnetic zigzag MO{sub 6} chains

Abstract

Two new isotypic phosphates LiNi{sub 2}H{sub 3}(P{sub 2}O{sub 7}){sub 2} (1) and LiCo{sub 2}H{sub 3}(P{sub 2}O{sub 7}){sub 2} (2) have been hydrothermally synthesized and structurally characterized by the single-crystal X-ray diffraction technique. They crystallize in the monoclinic space group C2/c with the lattice: a=10.925(2) A, b=12.774(3) A, c=8.8833(18) A, {beta}=123.20(3){sup o} for 1 and a=10.999(2) A, b=12.863(3) A, c=8.9419(18) A, {beta}=123.00(3){sup o} for 2. The transition metal atoms are octahedrally coordinated, whereas the lithium and phosphorus atoms are all tetrahedrally coordinated. As the lithium-induced derivatives of MH{sub 2}P{sub 2}O{sub 7} (M=Ni, Co), 1 and 2 possess the same structure with MH{sub 2}P{sub 2}O{sub 7} in terms of topology, comprising the MO{sub 6} zigzag chains and P{sub 2}O{sub 7} as the interchain groups. The magnetisms of 1 and 2 could be interpreted by adopting a quasi-one-dimensional (1D) zigzag chain model as that in their parent compounds: both 1 and 2 have ferromagnetic (FM) NiO{sub 6}/CoO{sub 6} chains; 1 shows a FM cluster glass behavior at low temperatures, which is originated from the possible antiferromagnetic (AFM) next-nearest-neighbour intrachain interactions; 2 shows a AFM ordering at T{sub N}=2.6 K and a metamagnetic transition at H{sub C}=4.2 kOe at 1.8 K. - Graphical abstract:more » LiNi{sub 2}H{sub 3}(P{sub 2}O{sub 7}){sub 2} (1) and LiCo{sub 2}H{sub 3}(P{sub 2}O{sub 7}){sub 2} (2) have been hydrothermally synthesized and structurally characterized. The MO{sub 6} octahedra share edges forming zigzag chains with P{sub 2}O{sub 7} as the interchain groups. Both of them are quasi-one-dimensional magnets and have ferromagnetic MO{sub 6} chains; 1 is a ferromagnet, whereas 2 is a metamagnet.« less
