Reactions of halides with trans-[Re(CO)(4)(MeCN)(NS)][AsF6](2): Syntheses and structures of trans-[Re(CO)(4)Cl(NS)][AsF6] and [(OC)(5)ReN S-N=S-N[Re(CO)(5)]S{=N-S NRe(CO)(5)}-CH2-CH2][AsF6](2), an unusual trinuclear bis(thiazyl)rhenium complex

From the reactions of trans-[Re(CO)(4)(MeCN)(NS)][AsF6](2) with CsCl, trans-[Re(CO)(4)Cl(NS)][AsF6]. MeCN 2 is formed, and with CsF [{Re(CO)(5)}(3)(C2H2N5S4)][AsF6](2) 3 is isolated; the X-ray crystal structures of 2 and 3 are reported.
