چکیده
The title complex, [Mo(C(15)H(22)BN(6))(C(7)H(7)O)(2)(NO)], contains an {MoNO}(4) core stabilized by κ(3)--hydrotris-(3,5-dimethyl-pyrazol-1-yl)borate, [Tp(Me2)](-), and two anionic m-cresolate ligands, leading to a distorted octa-hedral geometry for the Mo atom. The short Mo-O bond lengths [1.935 (2) and 1.971 (2) Å], as well as large Mo-O-Csp(2) angles [134.2 (2) and 143.54 (19)°], indicate dπ(Mo)-pπ(O) inter-actions, which are clearly weaker when compared with {Mo(NO)(Tp(Me2))} alkoxides. The nitrosyl system is virtually linear [179.3 (3)°] with Mo-N and N-O bond lengths of 1.760 (2) and 1.205 (3) Å, respectively. Intra- and inter-molecular C-H((Ph or CH(3)))⋯π((Ph)) inter-actions between adjacent phenyl rings are found in the crystal structure (d(H⋯Ph) in the range 2.743-2.886 Å). One of the Ph rings shows disorder, i.e. swinging in the ring plane.

The binuclear title complex, [Zn2(C33H33N6O)(CH3COO2)(CH3OH)](ClO4)2, was synthesized by the reaction between 2,6-bis-({[bis-(pyridin-2-yl)meth-yl]amino}-meth-yl)-4-methyl-phenol (H-BPMP), Zn(OAc)2 and NaClO4. The two Zn(II) ions are bridged by the phenolate O atom of the octadentate ligand and the acetate group. An additional methanol ligand is terminally coordinated to one of the Zn(II) ions,...
