Methyl substituent at C(2) carbon of acetophenone thiosemicarbazone induces unusual heterobridging in the [(Ph(3)P)Cu(mu-I)(2)(mu-S-Haptsc)Cu(PPh(3))] dimer.
The sulfur of acetophenone thiosemicarbazone {(Ph)(Me)C=N-NH-C(=S)NH(2); Haptsc} and two iodine atoms form an unusual heterobridge in the dinuclear complex [(Ph(3)P)Cu(mu-I)(2)(mu-S-Haptsc)Cu(PPh(3))] (1), leading to a short Cu--Cu distance of 2.504(1) Angstrom. This uncommon heterobridging is attributed to the presence of a methyl substituent at the Schiff base C2 carbon atom of the acetophenone thiosemicarbazone.
