Ml. Tong et al., Synthesis and structure of a photoluminescent three-dimensional network [AgL(MeCN)] (L=4,5-dichloro-2-cyano-3,6-dione-1,4-cyclohexen-1-ol anion), INORG CH C, 3(12), 2000, pp. 694-696
A three-dimensional coordination network of [AgL(MeCN)](infinity) (L = 4,5-
dichloro-2-cyano-3,6-dione-1,4-cyclohexen-1-ol anion) has been synthesized
and crystallographically characterized. The silver(I) atom in the title com
pound is coordinated by two chelating oxygen atoms from one L ligand and tw
o nitrogen atoms from an MeCN ligand and a cyano group of another L ligand
at the equatorial positions. and by one oxygen atom from the third L ligand
at the apical direction, completing a distorted square pyramidal geometry.
Each L ligand acts in mu (4)-mode to link three silver(I) atoms into a thr
ee-dimensional network, which shows room-temperature emission upon photoexc
itation at 350 nm. (C) 2000 Published by Elsevier Science S.A.
