摘要：

A spiral hexanuclear antiferromagnetic Cu(II) complex with a [Cu 3 (mu(2)-NO)(3)(mu(3)-O)] triangular core has direct metal spin coupling through diazine (mu(2)-NN), oxime (mu(2)-NO) and oxide/hydroxide (mu(3)-O) bridges. Spin frustration, expected in the triangular core, is suppressed (frustrated) by the bridging antiferromagnetic connections to the external metals, and so any residual spin in the triangle effectively cannot be stabilized.
