Abstrakt: As part of our studies on the synthesis and the characterization of oxalate-bridged compounds M-ox-M (ox = oxalate dianion and M = transition metal ion), we report the crystal structure of a new oxalate-bridged Mn(II) phase, {(CH6N3)[Mn(C2O4)Cl(H2O)]·H2O} n . In the compound, a succession of Mn(II) ions (situated on inversion centers) adopting a distorted octa-hedral coordination and bridged by oxalate ligands forms parallel zigzag chains running along the c axis. These chains are inter-connected through O-H⋯O hydrogen-bonding inter-actions to form anionic layers parallel to (010). Individual layers are held together via strong hydrogen bonds involving the guanidinium cations (N-H⋯O and N-H⋯Cl) and the disordered non-coordinating water mol-ecule (O-H⋯O and O-H⋯Cl), as well as by guanidinium π-π stacking. The structural data were confirmed by IR and UV-Visible spectroscopic analysis.
