Zero-field unpolarized neutron powder diffraction has been used to study the low-T magnetic structure and {ital T}-dependent crystal structure of M[N(CN){sub 2}]{sub 2} (M=Co,Ni). Both compounds show collinear ferromagnetism with spin orientation along the {ital c} axis. The results provide the determination of a complete magnetic structure in the ordered state for a molecule-based magnet. The {ital c} lattice parameter exhibits negative thermal expansion, explained by a wine-rack-like deformation. {copyright} {ital 1999} {ital The American Physical Society}
