Two for one: Two unusual magnets based on the [Mo(CN)7]4− building block with MnII linkers have been prepared with different topological 3D networks. Conversion of one into the other is triggered by dehydration during a single-crystal to single-crystal event (see picture; Mn: dark red, Mo: pink, C: green, N: blue, O: red).
