• -assisted hydrogen-bonded framework (CAHOF), as was the case when multitopic guanidinium or amidinium cations were combined with polycarboxylates, polysulfonates, or polyphosphonates [30][31][32][33]. The synthesis of a HOF or CAHOF consists of simply mixing the two components together [29]. An additional

Keywords: biomimetic synthesis; C1 building blocks; phosphorylation; polyphosphonates; synthetic methods; Introduction Methylidynetrisphosphonic acid, HC(PO3H2)3, or more commonly methylidynetrisphosphonates, XC(PO3R2)3, also

• called methanetrisphosphonates, are representatives of geminal polyphosphonates among which methylenebisphosphonates, H2C(PO3R2)2, are well-known as metabolically stable analogues of the naturally occurring inorganic pyrophosphate (PPi) [1][2][3]. Bisphosphonates are widely used drugs for the treatment
