Synthesis, crystal structure, and properties of [Cu(LH)](2)[M(mnt)(2)] [M = Ni or Cu; H2L=3,3 '-(1,3-propanediyldinitrilo)-bis(2-butanone oxime); mnt(2-) = maleonitriledithiolate] complexes containing bridging cyano groups

Interesting complexes containing a mnt(2-) bridge, based on the reaction of [M(mnt)(2)](2-) [M = Ni or Cu] with [Cu(LH)](+), have been prepared and ch aracterized by e.s.m.s., i.r and u.v-vis. spectroscopic techniques and by e lectrochemistry. The complexes show weak antiferromagnetic interactions bet ween magnetic centers. The X-ray analysis of the molecular structure of [Cu (LH)](2)[Ni(mnt)(2)] has been completed. It structurally features the CN gr oup of mnt(2-) which can act as a bridging ligand between two transition me tals.
