Magnetic properties of triangulo cobalt–hydride cluster [H3Co3(μ2-CO)3(PMe3)6]
摘要:
Transformation of [HCo(CO)(PMe3)(3)] in tetrahydrofuran under argon at 90 degrees C yields a solid cobalt-hydride cluster [H-3(Co(CO)(PMe3)(2))(3)]. The magnetic susceptibility down to 3.8 K confirms an antiferromagnetic coupling within the Co, ring and the Co-H interaction is of the antiferromagnetic nature as well: J(Co-Co) = - 192.4 cm(-1), J(H-Co) = - 570.0 cm(-1) and g(Co) = 2.402.
