and refined by the fullꢀmatrix leastꢀsquares method against F
with anisotropic displacements parameters for all nonhydrogen
atoms. Fourier analysis of the electron density distribution
showed that the Pd and Co atoms in molecule 1 are disordered
over two positions with equal occupancies. The distance beꢀ
tween two positions in the structure of 1 is ~0.4 Å. All calcuꢀ
