title: Novel layered ruthenium diphosphonate containing a mixed valent diruthenium paddlewheel core.
abstract: This paper reports the synthesis and crystal structure of a novel mixed valence ruthenium(II,III) compound, (NH(4))(3)Ru(2)(hedp)(2).2H(2)O (1), where hedp represents 1-hydroxyethylidenediphosphonate. It has a two-dimensional structure in which the paddlewheel diruthenium(II,III) units of Ru(2)(hedp)(2) are cross-linked through the phosphonate groups. The layers are stacked along the [100] direction with strong intra- and interlayer hydrogen bonds. Primary magnetic results are presented.
