Embodiment 1
[0022] Example 1 Preparation of a powder sample of the three-dimensional 4f-5d coordination polymer 1 of Ln=La:
[0023] La(NO 3 ) 3 ·6H 2 O(0.20mmol) and [HN(n-C 4 h 9 ) 3 ] 3 [W(CN) 8 ]·4H 2 O (0.20mmol) was mixed in acetonitrile (40mL) to obtain a two-dimensional layered coordination polymer La(H 2 O) 5 W(CN) 8 . La(H 2 O) 5 W(CN) 8 (0.20mmol) and the columnar ligand pyrazine (0.60mmol) were mixed in acetonitrile (55mL) to obtain a three-dimensional 4d-5f coordination polymer [La(H 2 O) 4 (pyrazine) 0.5 ]W(CN) 8 (1).
Embodiment 2
[0024] Example 2 Preparation of a powder sample of the three-dimensional 4f-5d coordination polymer 2 of Ln=Ce:
[0025] Ce(NO 3 ) 3 ·6H 2 O(0.20mmol) and [HN(n-C 4 h 9 ) 3 ] 3 [W(CN) 8 ]·4H 2 O (0.20mmol) was mixed in acetonitrile (40mL) to obtain a two-dimensional layered coordination polymer Ce(H 2 O) 5 W(CN) 8 . Ce(H 2 O) 5 W(CN) 8 (0.20mmol) and the columnar ligand pyrazine (0.60mmol) were mixed in acetonitrile (55mL) to obtain a three-dimensional 4d-5f coordination polymer [Ce(H 2 O) 4 (pyrazine) 0.5 ]W(CN) 8 (2).
Embodiment 3
[0026] Example 3 Preparation of powder sample of Ln=Pr three-dimensional 4f-5d coordination polymer 3:
[0027] Pr(NO 3 ) 3 ·6H 2 O(0.20mmol) and [HN(n-C 4 h 9 ) 3 ] 3 [W(CN) 8 ]·4H 2 O (0.20mmol) was mixed in acetonitrile (40mL) to obtain a two-dimensional layered coordination polymer Pr(H 2 O) 5 W(CN) 8 . Pr(H 2 O) 5 W(CN) 8 (0.20mmol) and the columnar ligand pyrazine (0.60mmol) were mixed in acetonitrile (55mL) to obtain a three-dimensional 4d-5f coordination polymer [Pr(H 2 O) 4 (pyrazine) 0.5 ]W(CN) 8 (3).
