  The structures of six new derivatives of copper(I) dicyanamide (dicyanamide = N(CN)2−, dca) have been determined. Those of Cu(dca)(MeCN) 1 and Cu(dca)(Me4pyz)1/22, Me4pyz = tetramethylpyrazine, both contain (6,3) sheets. Cu2(dca)2(bipy)(MeCN)2·0.5bipy 3, bipy = 4,4′-bipyridine, consists of 1-D ladder-like polymers with intercalated bipy guests. Cu4(dca)4(bipy)3(MeCN)24 is composed of 2-D layers which each interpenetrate with four others in a parallel fashion, resulting in a novel 3-D interlocking of layers. α-Cu(dca)(bpe) 5, bpe = 1,2-bis(4-pyridyl)ethene, consists of 2-D (4,4) sheets displaying twofold parallel interpenetration, while β-Cu(dca)(bpe) 6 contains five diamond-like networks which interpenetrate in an unprecedented fashion.

  The coordination polymers [M(dca)2pyz] (M=Mn, Fe, Co, Ni, Zn) have been synthesized and characterized by single-crystal and powder X-ray diffraction. Two isomers have been observed. The α compounds contain two interpenetrating 3D α-Po related networks. Bidentate dca ligands bridge the metal atoms to form square-grid-like M(dca)2 sheets, with the pyrazine ligands linking these sheets together to form

  We have conducted microwave-loss studies on organic superconductors. We report measurements on a series of crystals prepared from the bis(ethylenedithio)tetrathiafulvalene (ET) donor: alpha-(ET)2I3, beta-(ET)2I3, kappa-(ET)2Cu(NCS)2, kappa-(ET-d8)2Cu(NCS)2, and kappa-(ET)2Cu[N(CN)2]Br. All compounds show clear evidence for superconductivity, although there is a marked difference in the quality of the crystals as reflected in the microwave signals. The latter three materials show sharp, well-defined transitions that are comparable to those observed in the high-T(c) superconductors, and they exhibit highly anisotropic vortex motion. We confirm the T(c) of 11.6 K for the organic superconductor kappa-(ET)2Cu[N(CN)2]Br, which is 2-3 K higher than that of kappa-(ET)2Cu(NCS)2. We also confirm the approximately 0.5-K isotopic enhancement in the T(c) of kappa-(ET-d8)2Cu(NCS)2. The microwave-loss experiment is ideally suited for the search for superconductivity in organics and the experiment may be performed with the ease and quantity of material required for a melting-point determination-the measurement is nondestructive, contactless, and may be carried out on microgram samples.
