✦ Synopsis

Reaction of Ag(BF 4 ) with [n-Bu 4 N][TCNQ] in CH 3 CN yields a new phase of Ag(TCNQ) referred to as phase I (1).

A second polymorph of Ag(TCNQ), denoted phase II (2), which had earlier been prepared by electrocrystallization methods, can be accessed directly from silver powder and neutral TCNQ. The products were characterized by a combination of spectroscopic and physical methods. A powder X-ray di4raction pattern of (1) was indexed as a tetragonal cell with a ‫؍‬ b ‫؍‬ 12.1422 A > ,

The transport and magnetic properties of pure Y-Ba-Cu-O and Y-Ba-Cu-O/Ag composites prepared by the co-precipitation method have been studied. The normal state resistivity decreases with addition of silver. The magnetic properties reveal that addition of silver to the YBCO sample degrades the superc
