| Abstract: | Two new charge transfer salts of TTF with the counter anions M(phen)(CN)4]− (phen = 1,10-phenanthroline, M = Cr (I) and Fe (II)) are described. The structures consist of alternating stacks of dimerised TTF+ cations and M(phen)(CN)4]− anions and they are linked together by many short S?S contacts and hydrogen bonds. Within the organic stack, two dimerised TTF+ cations are arranged in a slipped face-to-face mode with short intra-dimer and long inter-dimer S?S distances. Strong antiferromagnetic exchange was found in the TTF+ dimers. Conductivity measurements show that compound I is a semiconductor. |
