摘要：

Flanked by [PW9O34] and [WO6] units, the Ni3II cluster in the salt 1 is magnetically isolated. Within this triangulo Ni3II cluster, however, ferromagnetic exchange interactions take place. According to magnetic measurements mu(eff) increases with decreasing temperature to a value of 8.1-mu(B) mol-1 at 5 K, supporting a spin ground state of S = 3.
