Two-Step Solvothermal Preparation of a Coordination Polymer Containing a Transition Metal Complex Fragment and a Thiostannate Anion:  [{Mn(en)₂}₂(μ-en)(μ-Sn₂S₆)]_∞ (en, Ethylenediamine)

Abstract

A two-step solvothermal synthetic method was used for preparation of a one-dimensional compound, [{Mn(en) 2 } 2 (µ-en)(µ-Sn 2 S 6 )] ∞ (1), in which the Mn(II) ions are bridged by thiostannate [Sn 2 S 6 ] 4anions and linear coordinating ethylenediamine (en) molecules. At first, a clear yellow solution containing [Sn 2 S 6 ] 4anions was previously obtained from a SnCl 4 /S/en mixture under solvothermal conditions. Then MnCl 2 ‚6H 2 O was added to the resulted solution, and the solvothermal reaction went on for additional days. Finally pale-yellow crystals of 1 were obtained. Using the same starting materials and in the same molar ratio, however, we obtained a colorless [Mn(en) 3 ] 2 Sn 2 S 6 (2) by the one-step, one-portion solvothermal reaction from a MnCl 2 /SnCl 4 /S/en mixture.

Solvothermal syntheses of three new one-dimensional ternary selenidostannates: [DBNH][M1/2Sn1/2Se2] (M=Mn, Zn, Hg)

“…In contrast to a great progress have been made in synthesizing 1D binary chalcogenides based on group 13 and 14 metals, 1D heterometallic chalcogenides deserve to pay more attentions due to their potentials in achieving colourful structures [53,54]. Divalent transition metal cations (Mn 2+ , Zn 2+ , Cd 2+ , Hg 2+ ) are usually used to enrich the structures of 1D chain by directly engaging in the construction of inorganic chain [31,[55][56][57][58][59][60][61][62], or chelating with multidentate amines to generate unsaturated transition-metal complexes, which may coordinate with chalcogen atoms of inorganic chain [6,[63][64][65]. On the other hand, hybridize transition metals with group 13 and 14 metals may regulate the chemical and physical properties of 1D chain.…”

“…[ 4-. Charge compensation is achieved by different cations including main group metal cations, [1][2][3][4][5][6][7][8][9] combinations of main group and transition metal cations, [10][11][12][13][14][15][16][17][18][19][20][21][22] transition metal cations and/or complexes, [23][24][25][26][27][28][29][30][31][32][33][34] and organic ammonium and/or metal cations. [35][36][37][38][39][40] Several of these compounds exhibit interesting physico-chemical properties like second harmonic generation, [17,18] efficient ion exchange behavior for rare earth cations, [41] promising properties as anode materials in lithium ion batteries, [39] selective heavy metal cation sequestration from aqueous solutions, [8] photoconductivity,…”

Two types of lanthanide selenidostannates(iv) first prepared under the same solvothermal conditions

“…7 The d-block TM ions (TM = Cr, Mn, Fe, Co, Ni) are easily chelated by organic amines to form either saturated or unsaturated TM complexes. The saturated TM complexes act as space fillers and charge compensating ions in chalcogenidostannates, such as [TM(en) 3 11 The unsaturated TM complexes can effectively incorporate into the chalcogenidostannate frameworks to form novel hybrid chalcogenidostannates with diverse structures, such as {Mn(en) 2 } 2 (μ-en)(μ-Sn 2 S 6 )] n , 12 Recently, there has been considerable interest in the use of lanthanide complexes as structure-directing agents instead of TM complexes in making chalcogenidometalate materials, because lanthanide complexes can integrate their optical, electrical and magnetic properties with the unique properties of the inorganic chalcogenidometalate framework, which helps to provide complementary properties and synergistic effects. 20 By employing lanthanide complexes as structure-directing agents, a number of organic hybrid lanthanide chalcogenidoantimonates and chalcogenidoarsenates have been prepared.…”
