 Reactions of the Dirhenium(II) Complexes Re2X4(\m-dppm)2 (X = Cl, Br;
 dppm = Ph2PCH2PPh2) with Isocyanides. 21.1A Comparison with the Complexes
 Re2Cl4(\m-dppE)2 and Re2Cl4(\m-dcpm)2 (dppE = Ph2PC(CH2)PPh2; dcpm =
 Cy2PCH2PCy2) and the Structural Characterization of Complexes of the
 Types Re2Cl4(\m-LL)2(CNR), Re2Cl4(\m-LL)2(CNR)2, and
 [Re2Cl3(\m-LL)2(CNR)3]+ (LL = dppm, dppE, dcpm; R =t-Bu, Xyl)
