“…All solvents were freshly distilled under argon prior to use. Deuterated solvent (CD 2 Cl 2 ) was dehydrated over CaH 2 and was distilled and degassed by three freeze-pump-thaw cycles prior to use. Bis(diphenylphosphino)methane (dppm) from Sigma Aldrich (St. Louis, MO, USA) was used without additional purification.…”

“…The concept of cooperative catalytic effects [1] in multinuclear transition metal systems led to the broad development and extensive investigation of the chemistry of transition metal complexes, bearing "short-bite" ligands that are able to lock two or more metallocenters in close proximity [2][3][4][5][6][7]. Such compounds are of great interest due to their catalytic activity including the transformation of small molecules on metal centres [8,9], they can also be used as synthetic models of enzyme action [10][11][12].…”

“…Among various types of diphosphine ligands, bis-(diphenylphosphino)methane (dppm) is one of the very efficient bridging ligands [2]. As other diphosphine ligands it is able to chelate metals, but rarely acts as a bidentate ligand (η 2 -dppm), forming a strained four-membered cycle (Scheme 1) [13][14][15][16][17].…”

“…Our studies of intermolecular interactions of BH 4 − [65,66] and several metal tetrahydroborates [67][68][69][70] with proton donors have shown the versatility of dihydrogen bonded (DHB) complexes formed and their crucial role in the reactivity of these compounds. In particular, we have shown that the formation of bifurcate DHB complexes involving both bridging and terminal hydride hydrogens of (Ph 3 P) 2 Cu(η 2 -BH 4 ) (Scheme 2) is prerequisite for the subsequent proton transfer and dimerization to occur [67]. Continuing these studies, we attempted the synthesis of (η 2 -dppm)Cu(η 2 -BH 4 ) following the published recipe [71].…”

“…The reaction mixture was stirred for 3 h at 60 • C, then cooled to room temperatures and refrigerated (−15 • C) to afford the white powder precipitate (0.3 g) of pure µ 2 -bis(diphenylphosphino)methane copper(I) tetrahydroborate (yield: 48%). The monocrystals suitable for XRD analysis were obtained by slow solvent evaporation from CH 2 …”

Bis(diphenylphosphino)methane copper(I) tetrahydroborate was synthesized by ligands exchange in bis(triphenylphosphine) copper(I) tetrahydroborate, and characterized by XRD, FTIR, NMR spectroscopy. According to XRD the title compound has dimeric structure, [(µ 2 -dppm) 2 Cu 2 (η 2 -BH 4 ) 2 ], and crystallizes as CH 2 Cl 2 solvate in two polymorphic forms (orthorhombic, 1, and monoclinic, 2) The details of molecular geometry and the crystal-packing pattern in polymorphs were studied. The rare Twisted Boat-Boat conformation of the core Cu 2 P 4 C 2 cycle in 1 is found being more stable than Boat-Boat conformation in 2.

Organophosphorus compounds of various types are among the most important classes of ligands in the coordination chemistry of the transition elements. This is particularly true for the tertiary phosphines R 3 P, which are known to stabilize complexes of metals in low oxidation states, while secondary and primary phosphines, R 2 HP and RPH 2 , are less common. The donor properties and the stereochemistry can be tuned by using carefully designed substitution patterns. More recently, organophosphorus compounds with low‐coordinate phosphorus atoms have also been employed as ligands in metal complexes. These include mainly phosphaalkenes and phosphaalkynes, phosphinidenes, diphosphenes, phosphinines, phosphonium cations, and even elemental phosphorus.
