Reaction of Ni(ClO 4 ) 2 ·6H 2 O with bis(3‐aminopropyl)amine (dpt) and ammonium thiocyanate produces the novel thiocyanato‐bridged nickel( II ) compound [Ni(μ‐NCS)(dpt)(NCS)] 2 [Ni(μ‐NCS)(dpt)(NCS)] 4 , which has been structurally characterised. The structure determination reveals that there are two different molecules in the crystal lattice; one is dinuclear and other is tetranuclear. Low‐temperature magnetic measurements show that there are ferro‐ as well as antiferromagnetic interactions. The ferromagnetic interaction arises from the dinuclear part and the doubly bridged part of the tetranuclear unit; the antiferromagnetic interaction occurs between singly bridged nickel centres in the tetranuclear unit.
