Context.  Formaldehyde H 2 CO was the first organic polyatomic molecule discovered in the interstellar medium to have been detected in a variety of sources. However, pathways to synthesize this molecule under interstellar conditions have yet to be discussed.   Aims.  We carried out a systematic study to analyze the chemical processes that can explain the H 2 CO formation mechanism toward a decamer of methanol (CH 3 OH) 10  as target material to mimic an ice mantle bombarded by an OH +  cation.   Methods.  We performed Born-Oppenheimer (ab initio) molecular dynamics simulations to obtain the formation mechanisms of complex organic molecules (COMs) such as formaldehyde H 2 CO and its HCOH isomer.   Results.  We found that CH 2 OH +  and CH 2 (OH) 2  are the main precursors to form H 2 CO and HCOH. We discuss its formation mechanisms and the astrophysical implications in star-forming regions. These processes are likely relevant to the production of COMs.
