摘要：The present study describes the designed synthesis, X-ray structures, and magnetic properties of two 2D cyano bridged heterobimetallic W-V-Co-II networks, {[W(CN)(8)](2)[Co(phpy)(4)](3)}center dot 2CH(3)OH center dot 2H(2)O (1) and {[W(CN)(8)](2)[Co(4-spy)(4)](3)}center dot 6H(2)O (2) (phpy = 4-phenylpyridine, 4-spy = 4-styrylpyridine). Both compounds consist of cyano-bridged 12-metal 36-membered ring units, Co6W6(CN)(12), joined by organic linkers into a 2D plane. The layer presents a corrugated configuration in compound 1 and a plane configuration in compound 2 due to different p-p stacking interactions. Magnetic measurements reveal that both 1 and 2 have a transition to the spin glass-like phase due to competitive magnetic interactions.
