Abstract

Reaction of copper perchlorate with sodium nitrite and pyrazine in methanol gives rise to the compound [Cu 2 (pyrazine) 3 (CH 3 O) 2 ](ClO 4 ) 2 ( 1 ). This complex has been characterized through IR, combustion analysis, single crystal X-ray diffraction, and temperature dependent magnetic susceptibility measurements. Compound 1 crystallizes in the triclinic space group P-1 with the copper coordination geometry being nearly square pyramidal. The Cu(II) ions are bridged by the methoxide ions to form a dimeric structure. Compound 1 exhibits an extended 3-D network with pyrazine rings forming sheets of the copper dimers, and bridging those sheets to form a distorted honeycomb. Magnetic susceptibility measurements show a strong antiferromagnetic exchange within the methoxy-bridged copper dimers with 2J ~ -880K.
