摘要	Two structural polymorphs of CdP2, including orthorhombic α-CdP2 (Pna21) and tetragonal β-CdP2 (P41212/P43212), were synthesized through one chemical transport reaction and one solid-state reaction, respectively. Their three-dimensional (3D) framework consisted of ∞1[P-] polyanion chains and CdP4 tetrahedra. Remarkably, α-CdP2 exhibited excellent comprehensive optical properties, including a strong SHG effect (3.2× AgGaS2), large birefringence (Δn = 0.138), high LIDT (10.1× AgGaS2), and wide IR transparent range, which suggested that α-CdP2 was a promising IR NLO material. Theoretical studies also revealed that the large SHG effect and birefringence originated from the synergism of its parallel polar ∞1[P-] polyanion chains and distorted CdP4 tetrahedra, in which the charge transfers from πpz(P1-P2) to σ(Cd-P1) and πpy(P1-P2) were responsible for the large SHG effect and birefringence. This indicated that P-P homoanion bonds could be adapted to design the IR NLO crystal with large SHG effects and moderate band gaps. ©
