Preparation

Manganese(II) chloride is prepared by heating manganese(II) oxide, manganese dioxide, manganese(II) carbonate or manganese(II) hydroxide with hydrochloric acid: MnO2 + 4HCl → MnCl2 + 2H2O + Cl2 MnCO3 + HCl → MnCl2 + H2O + CO2 When the product mixture is evaporated below 58°C, the tetrahydrate salt, MnCl2?4H2O is obtained. Manganese(II) chloride is a by-product in the manufacture of chlorine from manganese dioxide and hydrochloric acid (the Weldon process). Anhydrous chloride can be prepared by heating manganese(II) oxide or manganese(II) carbonate with dry hydrogen chloride; or by burning the metal in chlorine at 700°C to 1,000°C. The anhydrous salt can also be obtained by slowly heating the tetrahydrate, MnCl2?4H2O in a rotary drier above 200°C or by dehydration in a stream of hydrogen chloride gas.

Reactions

Manganese(II) chloride forms double salts with alkali metal chlorides when mixed in stoichiometric amounts. Such double salts, which can decompose in water, may have compositions like KMnCl3 or K2MnCl4. Manganese(II) chloride forms adducts with ammonia, hydroxylamine and many other nitrogen compounds. Many adducts are stable at ordinary temperatures. Examples are MnCl2?6NH3 and MnCl2?2NH2OH. An aqueous solution can readily undergo double decomposition reactions with soluble salts of other metals, producing precipitates of insoluble salts of Mn(II) or other metals.

Safety Profile

Poison by intraperitoneal, subcutaneous, intramuscular, intravenous, and parenteral routes. Moderately toxic by ingestion. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental carcinogenic data. Mutation data reported. Explosive reaction when heated with zinc foil. Reacts violently with potassium or sodium. When heated to decomposition it emits toxic fumes of Cl-. See also MANGANESE COMPOUNDS and CHLORIDES.

Check Digit Verification of cas no

The CAS Registry Mumber 7773-01-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,7 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7773-01:
(6*7)+(5*7)+(4*7)+(3*3)+(2*0)+(1*1)=115
115 % 10 = 5
So 7773-01-5 is a valid CAS Registry Number.

MASS-SPECTROMETRIC MEASUREMENTS OF THERMODYNAMIC PROPERTIES OF THE MOLTEN KCl-MnCl2 SYSTEM.

Sasamoto,Itoh,Sata

, p. 2415 - 2419 (1983)

Activities and heats of mixing for the molten KCl-MnCl//2 system were determined mass-spectrometrically by the ion-current ratio method. Activities of components KCl and MnCl//2 show large negative deviations from Raoult's law, indicating a very strong interaction between KCl and MnCl//2. Entropies of mixing calculated from measured activities and heats of mixing have minimum values in the vicinity of 33% MnCl//2, and have been compared with those calculated on the basis of some molten structure models to infer possible chemical species in the molten salt.

Enhanced Stability of the FeII/MnII State in a Synthetic Model of Heterobimetallic Cofactor Assembly

Kerber, William D.,Goheen, Joshua T.,Perez, Kaitlyn A.,Siegler, Maxime A.

, p. 848 - 857 (2016)

Heterobimetallic Mn/Fe cofactors are found in the R2 subunit of class Ic ribonucleotide reductases (R2c) and R2-like ligand binding oxidases (R2lox). Selective cofactor assembly is due at least in part to the thermodynamics of MII binding to the apoprotein. We report here equilibrium studies of FeII/MnII discrimination in the biomimetic model system H5(F-HXTA) (5-fluoro-2-hydroxy-1,3-xylene-α,α′-diamine-N,N,N′,N′-tetraacetic acid). The homobimetallic F-HXTA complexes [Fe(H2O)6][1]2·14H2O and [Mn(H2O)6][2]2·14H2O (1 = [FeII2(F-HXTA)(H2O)4]-; 2 = [MnII2(F-HXTA)(H2O)4]-) were characterized by single crystal X-ray diffraction. NMR data show that 1 retains its structure in solution (2 is NMR silent). Metal exchange is facile, and the heterobimetallic complex [FeIIMnII(F-HXTA)(H2O)4]- (3) is formed from mixtures of 1 and 2. 19F NMR was used to quantify 1 and 3 in the presence of excess MII(aq) at various metal ratios, and equilibrium constants for FeII/MnII discrimination were calculated from these data. FeII is preferred over MnII with K1 = 182 ± 13 for complete replacement (2 21). This relatively modest preference is attributed to a hard-soft acid-base mismatch between the divalent cations and the polycarboxylate ligand. The stepwise constants for replacement are K2 = 20.1 ± 1.3 (2 23) and K3 = 9.1 ± 1.1 (3 21). K2 > K3 demonstrates enhanced stability of the heterobimetallic state beyond what is expected for simple MnII FeII replacement. The relevance to FeII/MnII discrimination in R2c and R2lox proteins is discussed.

Ferenc,Sadowski,Tarasiuk,Cristóv?o,Osypiuk,Sarzyński

, p. 2719 - 2727 (2017/12/26)

Complexes of 4-[(4-fluorophenyl)amino]-4-oxobut-2-enoic acid, HL, with Mn(II), Co(II), Ni(II), Cu(II), Nd(III), Gd(III), and Er(III) were synthesized and characterized by various physico-chemical methods: elemental analysis, FT-IR, TG, DTG, DSC, TG/FT-IR, XRF, XRD, and magnetic measurements using the Gouy’s method and a SQUID-VSM magnetometer. The complexes were found to be hydrates (except Er(III) complex) containing 1 to 4 molecules of water. The carboxylate groups acted as bidentate ligands.
