The local octahedral environment of Ni2+ in NiTiF6 ・ 6H2O and ZnSiF6 ・ 6H2O crystals with a trigonal distortion has been studied at different temperatures, based on the complete energy matrices. The calculated results showed that the local lattice structure around an octahedral Ni2+ centre in NiTiF6 ・ 6H2O and ZnSiF6 ・ 6H2O exhibits a compression distortion. Simultaneously, the orbital reduction effect on the g factors has been studied. The relationship between Δg = g||−g⊥ and orbital reduction factor k at 4.2, 77 and 298 (302) K has been discussed, suggesting that there is an almost linear relation between k and Δg for the Ni2+ ion in NiTiF6 ・ 6H2O and ZnSiF6 ・ 6H2O at each temperature.

A new octacyanotungstate(v) singe chain magnet with an effective energy barrier of 39.7(3) cm−1 is achieved by enforcing Ising-like magnetic anisotropy via introduction of trigonal distortion with a fac-tridentate capping ligand.
