The reaction of hexacyanochromate with connectivity 6 and a mononuclear Ni complex bearing a bulky tridentate macrocycle leads in one step to the formation of a nonanuclear Cr2Ni7 complex with central low spin and peripheral high spin Ni ions; fast tunnelling of the magnetization is observed at low temperature by micro-SQUID studies on a single crystal.
