  "abstract": "Three coordination compounds of formula [CoCl 2 ( N , N′ )] n [ N , N ' = 4,4′-bipyridine (4,4′-bpy), ( Cobpy ); trans -4,4′-azopyridine ( t -apy), ( Coapy ); and trans -1,2-bis(4-pyridyl)ethylene ( t -bpee), ( Cobpee )] have been prepared using solvothermal procedures. They have been characterized by different techniques, including the ab initio crystal structure determination of Cobpee . The structures of Cobpy and Cobpee are formed by octahedral tran s-CoCl 4 N 2 nodes, which construct rectangular grid layers that are stacked in an ABAB pattern. The three complexes show a similar metamagnetic behavior, which suggests that Coapy displays a layered structure equally built. The magnetic phase transitions of the compounds from an antiferromagnetic state to a paramagnetic-like or ferromagnetic-like state have been analyzed, and magnetic phase diagrams are provided. The use of N , N′ -donor ligands with different lengths allows controlling the strength of the interchain interactions and the critical temperature ( T c ) and critical magnetic field ( H c ) of the metamagnetic phase transitions.",
