The structure, photo-induced magnetization and correlation of the cyano-bridged two-dimensional hetero-bimetallic compounds

Two new 3d–4f cyano-bridged hetero-bimetallic compounds with distinguished two-dimensional honeycomb network structure, {Ln(HP)2(H2O)3(μ-NC)3Fe(CN)3}n, (Ln=Ce, Nd; HP=4-Hydroxypyridine) were synthesized and crystallographically characterized. A novel photo-induced magnetization phenomenon for {Nd(HP)2(H2O)3(μ-NC)3Fe(CN)3}n, was revealed and studied. Furthermore, the correlation between photo-induced magnetization and structure was proposed.
