Embodiment 1
[0047] Embodiment one: [Mn(trien)(N 2 h 4 ) 2 ]Hg 2 Te 4
[0048] MnCl 2 (0.031 g, 0.25 mmol), HgCl 2 (0.136 g, 0.50 mmol) and Te (0.255 g, 2 mmol) were added to 2.0 ml of hydrazine (N 2 h 4 ) and 1.0 ml of triethylenetetramine (trien) mixed solution, stirred for 10 minutes, put the mixture into a polytetrafluoroethylene-lined stainless steel reactor, and reacted at 100° C. for 5 days. After cooling to room temperature, black crystals were precipitated, filtered, washed with 5 ml of ethanol and acetone, and dried in vacuo to obtain 0.182 g of crystals with a yield of 62%. Elemental analysis: C 5.93, H 2.15, N 9.38%; theoretical value: C 6.12, H 2.23, N 9.52%. Infrared absorption spectrum data (KBr, cm -1 ): 3455(s), 3250(m), 2943(m), 2867(m), 1719(w), 1635(w), 1564(w), 1458(m), 1383(m), 1315(m ),1173(w),1135(w),1080(s),1004(s),946(s),883(s),816(s),706(w),592(s),483(s ), 429(m), 410(w). Solid State Absorption Spectrometry: Semiconductor Energy Gap E g = 0.84eV.

[0050] ZnCl 2 (0.035 g, 0.25 mmol), HgCl 2 (0.136 g, 0.50 mmol) and Te (0.255 g, 2 mmol) were added to 2.0 ml of hydrazine (N 2 h 4 ) and 1.0 ml of triethylenetetramine (trien) mixed solution, stirred for 10 minutes, put the mixture into a polytetrafluoroethylene-lined stainless steel reactor, and reacted at 100° C. for 5 days. After cooling to room temperature, black crystals were precipitated, filtered, washed with 5 ml of ethanol and acetone, and dried in vacuo to obtain 0.199 g of crystals with a yield of 67%. Elemental analysis: C 5.94, H 2.12, N 9.31%; theoretical value: C 6.07, H 2.21, N 9.44%. Infrared absorption spectrum data (KBr, cm -1 ): 3460(s), 3270(m), 3106(w), 2922(w), 2064(m), 1656(s), 1589(s), 1526(w), 1463(m), 1379(s ),1274(w),1118(s),1072(w),996(s),950(s),861(w),786(m),673(w),618(s),542(m ), 479(s), 424(m), 408(w). Solid State Absorption Spectrometry: Semiconductor Energy Gap E g = 0.8...

[0051] Embodiment three: [Fe(trien)(N 2 h 4 ) 2 ]Hg 2 Te 4
[0052] FeCl 2 (0.032 g, 0.25 mmol), HgCl 2 (0.136 g, 0.50 mmol) and Te (0.255 g, 2 mmol) were added to 2.0 ml of hydrazine (N 2 h 4 ) and 1.0 ml of triethylenetetramine (trien) mixed solution, stirred for 10 minutes, put the mixture into a polytetrafluoroethylene-lined stainless steel reactor, and reacted at 100° C. for 5 days. After cooling to room temperature, black crystals were precipitated, filtered, washed with 5 ml of ethanol and acetone, and dried in vacuum to obtain 0.191 g of crystals, with a yield of 65%. Elemental analysis: C 5.99, H 2.17, N 9.45%; theoretical value: C 6.12, H 2.23, N 9.51%. Infrared absorption spectrum data (KBr, cm -1 ): 3455(w), 3305(w), 3252(m), 3200(m), 2999(w), 2367(w), 1565(s), 1485(s), 1452(m), 1378(s ), 1207(w), 1109(w), 1024(s), 877(w), 744(w), 650(w), 510(m), 418(w).
