The crystal structures of dichloro- (2) and lmethylidene)-2-thienylmet
hylamine-N,N']copper(II) (1) have been determined to investigate the c
oordination of die metal centre. In both cases, the two N atoms and tw
o halogen anions are coordinated to the copper(II) and the S atom is f
ree. For the dibromo complex, the structure is monomeric, while die di
chloro complex forms dimers diylidene)-2-thienylmethyl-amine-N,N']copp
er(II)})
