Abstract

The structures of the tetranuclear silver(I), [Ag₄(hpp)₄], and the dinuclear gold(II), [Au₂(hpp)₂Cl₂], (hpp = 1,3,4,6,7,8-hexahydro-pyrimido[1,2-a]pyrimidinate) guanidinate-like bases are reported and show a silver–silver distance of 2.8614(6) Å and a gold–gold distance of 2.4752(9) Å, the shortest Au–Au bond heretofore reported.
