A hardwon dirhodium paddlewheel with guanidinate type (hpp) bridging ligands.
We report a dirhodium paddlewheel compound which has an Rh2(5+) core enveloped by four guanidinate ligands and an axially coordinated bromine atom; Rh2(hpp)4Br crystallizes as a 1-D chain with a Rh-Rh distance of 2.430(3) è and a Rh-Rh bond order of 1.5 (hpp = the anion of 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2a]pyrimidine).
