摘要：

Dinuclear metal carboxylates of Mo, Ru and Rh with 2 equiv. of 9-ethylguanine (9-EtGH) give complexes containing [M(2)(O(2)CR)(2)(9-EtGH)(2)(solv)(2)](2+) cations; structural characterization shows these to contain unusual N-7,O-6-bridging 9-EtGH groups in 'head-to-tail' (HT) or 'head-to-head' (HH) orientations, and establishes this bridging mode for metal-metal bond orders of 1-4.
