The reaction of W2(dmhp)4 (Hdmhp = 2,4-dimethyl-6-hydroxypyrimidine) with Li(PhN)2N gives only the product in which 2 dmhp ligands are replaced, in a transoid fashion, by 2 (PhN)2N- ligands. The orange cryst. compd. W2(dmhp)2(PhN)2N2.2THF is thermally stable but somewhat air-sensitive and only slightly sol. in THF. The compd. crystallizes in the space group C2/c with a 21.680(3), b 10.177(3), c 23.089(1)\AA, b 115.19(1)°, V = 4610(3)\AA3, and Z = 4 with the mols. lying on a crystallog. inversion center. The W-W distance of 2.169(1) \AA is very similar to that in W2(dmhp)4 and W2(dmhp)2(PhN)2CMe2.2THF. The structure was refined to final discrepancy factors of R1 = 0.040 and R2 = 0.055. on SciFinder(R)
