Preparation and properties of the dianion and the dihydro derivative of the bis[1,2,5]thiadiazolo derivative of tetracyanoquinodimethane
Abstract
The dianion of the bis[1,2,5]thiadiazolo derivative of tetracyanoquinodimethane (BTDA-TCNQ) was isolated as a stable sodium salt; the dihydro derivative of BTDA-TCNQ, containing the benzo[1,2-c: 4,5-c′]bis[1,2,5]thiadiazole skeleton, was found to be a strong dibasic acid.
