Proton Conductivity in Photomagnetic Cu^II₂-[M^IV(CN)₈] Frameworks (M = Mo^IV and W^IV) Facilitated by the Tetracarboxy-Derivative of Cyclam.

ABSTRACT: Two 3D bimetallic cyanido-bridged coordination polymers, [Cu^II(H₄tetac)]₂[M^IV(CN)₈]·4H₂O (M = Mo^IV (1) and W^IV (2)), based on copper(II) complex of tetracarboxylic-derivative of cyclam, H₄tetac (=1,4,8,11-tetrazacyclotetradecane-6,6,13,13-tetracarboxylic acid), have been synthesized and characterized in terms of structure, proton conductivity, and the photomagnetic effect. The isostructural compounds crystallize in the polar Fdd2 space group and present a diamond-like topology. The carboxylic groups in the structure yield proton conductivities of 5.4(3) × 10^-7 S cm^-1 (1) and 8.6(3) × 10^-7 S cm^-1 (2) at 298 K and 98
