  The nido-metalloborane complexes Ta-2(mu(2),eta(4)-B2H6)(DTolF)(4) . 2Et(2)O, 1, DTolF(-) = [(p-tolyl)NCHN(p-tolyl)](-), and Ta-2(mu(4)-B2H6)(DPhF)(4) . Et(2)O, 2, DPhF(-) = [phenylNCHNphenyl](-), are formed as the products of tantalum pentachloride with lithium borohydride followed by the addition of LiDTolF or LiDPhF. Complexes 1 and 2 are the first structurally characterized compounds in which two metal atoms that are bonded to each other are also bridged by an hexahydroborate ligand through four B-H-M three-center bonds in a symmetric bonding mode. The Ta-Ta distances are 2.725(1) Angstrom in 1 and 2.728(1), 2.736(1) Angstrom in 2. Crystallographic data are as follows: compound 1, P (1) over bar, a = 15.197(3) Angstrom, b = 15.675(2) Angstrom, c = 16.449(6) Angstrom, alpha = 102.50(1)degrees, beta = 99.04(1)degrees, gamma = 117.10(2)degrees, and Z = 2; compound 2, P (1) over bar with a = 11.547(5) Angstrom, b = 20.03(1) Angstrom, c = 29.934(8) Angstrom, alpha = 107.60(1)degrees, beta = 100.86(2)degrees, gamma = 95.65(2)degrees, and Z = 4. In these two molecules there are two ArNC(H)NAr- ligand coordinated in a chelating manner to each of two tantalum atoms. These two Ta(DTolF)(2) or Ta(DPhF)(2) fragments are united by a Ta=Ta bond (ca. 2.73 Angstrom), and a B2H6 unit lies across the bond forming two B-H-Ta bridge bonds to each tantalum atom. The B2H6Ta2 moiety constitutes a B2Ta2 nido-metalloborane, formally similar to B4H10.

  The purpose of this report is to call attention to the wide range of reactions that an amidine or amidinium may undergo in the presence of reduced metal ions, other than simple ligation of the metal ions. Crystal structures of five examples are presented. In (eta-dmpm)Cl2Ta(mu-NTol)(mu-eta(2)-HC=NTol)(mu-dmpm)TaCl(eta(2)-DTolF) (I), both fragments from a C-N bond cleavage of the di-p-tolylformamidinate anion, DTolF(-), namely tolylimido and tolylformimidoyl groups, are found forming bridges between the metal atoms. An amido group is also found in TaCl2(NPh)(DPhF)(HDPhF) (II), in which a six-coordinated tantalum atom is surrounded also by two chlorine atoms, a chelating diphenylformamidinate, DPhF(-) and a neutral HDPhF molecule. A new neutral chelating ligand forms during the synthesis of CoCl2(PhNCHNPhCHNPh) (III), in which the divalent cobalt atom is in a pseudo-tetrahedral environment. The six-membered metallocycle formed by th Co-N-C-N-C-N atoms is essentially planar. Reaction of K with crude Ta-2(mu(2)-eta(4)-B2H6)(mu-DTolF)(4) produces [(B2H5)N(Tol)C(H)N(Tol)]Ta(mu(2)-NTol)(2)(mu(2)-DTolF)(2)Ta[(Tol)NC(H)N(Tol)B2H5]. 2Et(2)O (IV), in which a ditantalum unit is bridged by two DTolF and two tolylimido groups. A new ligand formed by fusion of a B2H5- unit to a DTolF(-) anion chelates to each of the metal atoms. In the crystals, 50% of the B2H5 moieties are BH3 groups. Coupling of two DPhF anions is observed in PhNC(H)N(Ph)C(H)(NPh)(2)Ta(DPhF)(3) . Et(2)O (V). The new dianion chelates the metal center, to which three other DPhF groups are attached giving an eight-coordinated compound. Copyright (C) 1997 Elsevier Science Ltd.
